  • Batalin–Vilkovisky Structure on Hochschild Cohomology of Zigzag Algebra
           of Type $$\widetilde{\mathbf {A}}_{1}$$ A ~ 1

    • Free pre-print version: Loading...

      Abstract: In this paper, we study the Batalin–Vilkovisky structure on the Hochschild cohomology of quantum zigzag algebras \(A_{{\mathfrak {q}}}\) of type \(\widetilde{\mathbf {A}}_{1}\) . We first calculate the dimensions of Hochschild homology groups and Hochschild cohomology groups of \(A_{{\mathfrak {q}}}\) . Based on these computations, we determine the Hochschild cohomology ring of \(A_{{\mathfrak {q}}}\) , and give the Batalin-Vilkovisky operator and the Gerstenhaber bracket on Hochschild cohomology ring of \(A_{{\mathfrak {q}}}\) explicitly.

  • Local Conicity and Polyhedrality of Convex Sets

    • Free pre-print version: Loading...

      Abstract: A convex set in the n-dimensional vector space is called boundedly polyhedral provided its intersection with every polytope is a polytope (possibly empty). We refine existing results on bounded polyhedrality of line-free closed convex sets in terms of local conicity and local polyhedrality at their extreme points and halflines.

      Abstract: We study the new warped metric proposed by P. Marcal and Z. Shen. We obtain the differential equation of such metrics with vanishing Douglas curvature. By solving this equation, we obtain all Douglas warped product metrics. We show that Landsberg and Berwald warped product metrics are equivalent. We classify Douglas Ricci-flat metrics. Examples are included.

  • H.S.M. Coxeter’s Theory of Accessibility: From Mario Pieri to Marvin
           Greenberg

    • Free pre-print version: Loading...

      Abstract: In the 1960s, H. S. M. Coxeter adopted a set of incidence axioms similar to one O. Veblen and J. W. Young proposed in 1910, to study projective spaces for which a field of elements of a commutative number system is an algebraic model. Coxeter introduced a theory called “accessibility,” which is applicable to the study of conics defined in 1847 by G. K. C. von Staudt, and the partitioning of projective planes in terms of them. In a conversation of 1989, Coxeter revealed that he used ideas from an 1898 paper of M. Pieri to define the relation of accessible points in a continuity-independent projective plane. In 1979, M.J. Greenberg reinterpreted that relation in such a plane using incidence and order axioms from another of Coxeter’s works. We compare the axiomatic bases on which Coxeter, Greenberg, and Pieri construct projective planes with and without continuity, using synthetic methods to introduce analytic ones. We show how several of their publications intersect in significant ways. Other paths emerge from these investigations, such as one that examines the origins of a statement postulated by Pieri, often credited to Pasch, which Coxeter attributed to Veblen.

  • A Generalization of a Question Asked by B. H. Neumann

    • Free pre-print version: Loading...

      Abstract: Let \(w \in F_2\) be a word and let m and n be two positive integers. We say that a finite group G has the \(w_{m,n}\) -property if however a set M of m elements and a set N of n elements of the group is chosen, there exist at least one element \(x \in M\) and at least one element \(y \in N\) such that \(w(x,y)=1.\) Assume that there exists a constant \(\gamma < 1\) such that whenever w is not the identity in a finite group X, then the probability that \(w(x_1,x_2)=1\) in X is at most \(\gamma .\) If \(m\le n\) and G satisfies the \(w_{m,n}\) -property, then either w is the identity in G or G is bounded in terms of \(\gamma , m\) and n. We apply this result to the 2-Engel word.

      Abstract: In this work we establish the well-posedness of the Cauchy problem for a class of pseudodifferential diffusion equations on the torus. The class considered includes fractional diffusion equations and as a special case we consider fractional diffusion equations with drift. By applying toroidal pseudodifferential calculus we establish regularity estimates, existence and uniqueness with respect to the usual Sobolev spaces on the torus.

  • Sensitivity of Iterated Function Systems Under the Product Operation

    • Free pre-print version: Loading...

      Abstract: In this paper, \({\mathcal {F}}=\{X; f_\lambda \lambda \in \varLambda _1\}\) and \({\mathcal {G}}=\{Y; g_\gamma \gamma \in \varLambda _2\}\) are two iterative function systems defined on the compact metric spaces \((X,d_1)\) and \((Y,d_2)\) , respectively, where \(\varLambda _1,\varLambda _2\) are finite nonempty sets. The concepts of a stronger form of sensitive (i.e., ergodically sensitive, thickly syndetically sensitive, thickly sensitive, syndetically sensitive, cofinitely sensitive, Li–Yorke sensitive, and infinite sensitive) for iterated function systems are introduced. In particular, for every integer \(k\ge 2,k\in {\mathbb {N}}\) , it is shown that \({\mathcal {F}}\times {\mathcal {G}}\) and \({\mathcal {F}}^{k}\times {\mathcal {G}}^{k}\) are equivalent to Li–Yorke sensitive (resp., infinite sensitive, sensitive). What’s more, some necessary and sufficient conditions for \({\mathcal {F}}\times {\mathcal {G}}\) to be sensitive (resp., ergodically sensitive, thickly syndetically sensitive, thickly sensitive, syndetically sensitive, or cofinitely sensitive) are obtained.

  • Isometries and Approximate Local Isometries Between $$\mathrm {AC}^p(X)$$
           AC p ( X ) -Spaces

    • Free pre-print version: Loading...

      Abstract: Let X and Y be compact subsets of \(\mathbb {R}\) with at least two points. For \(p\ge 1\) , let \(\mathrm {AC}^p(X)\) be the space of all absolutely continuous complex-valued functions f on X such that \(f'\in L^{p}(X)\) , with the norm \(\left\ f\right\ _{\Sigma }=\left\ f\right\ _\infty +\Vert f'\Vert _p\) . We describe the topological reflexive closure of the set of linear isometries from \(\mathrm {AC}^p(X)\) onto \(\mathrm {AC}^p(Y)\) . Using this description, we prove that such a set is algebraically reflexive and 2-algebraically reflexive. Moreover, as another application, it is shown that the sets of isometric reflections and generalized bi-circular projections of \(\mathrm {AC}^p(X)\) are topologically reflexive and 2-topologically reflexive.

  • The Poincare Lemma for Codifferential, Anticoexact Forms, and Applications
           to Physics

    • Free pre-print version: Loading...

      Abstract: The linear homotopy theory for codifferential operator on Riemannian manifolds is developed in analogy to a similar idea for exterior derivative. The main object is the cohomotopy operator, which singles out a module of anticoexact forms from the module of differential forms defined on a star-shaped open subset of a manifold. It is shown that there is a direct sum decomposition of a differential form into coexact and anticoexat parts. This decomposition gives a new way of solving exterior differential systems. The method is applied to equations of fundamental physics, including vacuum Dirac-Kähler equation, coupled Maxwell-Kalb-Ramond system of equations occurring in a bosonic string theory and its reduction to the Dirac equation.

      Abstract: In the late 1990s, B. Y.

In this paper, we completely classify proper special slant surfaces with non-constant mean curvature in 2-dimensional complex space forms.

  • On n-saturated Closed Graphs

    • Free pre-print version: Loading...

      Abstract: Geschke proved in [2] that there is a clopen graph on \(2^\omega \) which is 3-saturated, but the clopen graphs on \(2^\omega \) do not even have infinite subgraphs that are 4-saturated; however there is \(F_\sigma \) graph that is \(\omega _1\) -saturated. It turns out that there is no closed graph on \(2^\omega \) which is \(\omega \) -saturated, see [3]. In this note we complete this picture by proving that for every \(n\in {\mathbb {N}}\) there is an n-saturated closed graph on the Cantor space \(2^\omega \) . The key lemma is based on probabilistic argument. The final construction is an inverse limit of finite graphs.

  • Quasi-Metric Properties of the Dual Cone of an Asymmetric Normed Space

    • Free pre-print version: Loading...

      Abstract: We obtain some quasi-metric properties of the dual cone of an asymmetric normed space. Thus, we prove that it is balanced, and hence its topology is completely regular. We also prove that it is complete in the sense of D. Doitchinov. These results generalize those obtained by Romaguera et al. In [18] because, in our study, the asymmetric normed space does not necessarily satisfy the \(T_1\) axiom. Moreover, we provide a class of asymmetric normed spaces whose dual cones are right K-sequentially complete. Finally, we represent an arbitrary asymmetric normed space as a function space by using the unit ball of its dual space.

  • Generalization of the Heyde Theorem to Some Locally Compact Abelian Groups

    • Free pre-print version: Loading...

      Abstract: According to the well-known Heyde theorem, the Gaussian distribution on the real line is characterized by the symmetry of the conditional distribution of one linear form of independent random variables given another. In the article we study analogues of this theorem for some locally compact Abelian groups. We consider linear forms of two independent random variables with values in a locally compact Abelian group X, whose characteristic functions do not vanish. Unlike most previous works, we do not impose any restrictions on coefficients of the linear forms. They are arbitrary topological automorphisms of X.

      Abstract: In this paper, we study the interesting open problem of classifying the locally strongly convex centroaffine Tchebychev hypersurfaces in \({\mathbb {R}}^{n+1}\) with constant sectional curvature. First, for arbitrary dimensions we solve the problem by assuming that the centroaffine shape operator vanishes. Second, extending the solved cases of \(n=2,3\) , we continue working with the case \(n=4\) . As the result, we establish a complete classification of the flat hyperbolic centroaffine Tchebychev hypersurfaces in \({\mathbb {R}}^5\) .

      Abstract: Zero mean curvature surfaces in the simply isotropic 3-space \({\mathbb {I}}^3\) naturally appear as intermediate geometry between geometry of minimal surfaces in \({\mathbb {E}}^3\) and that of maximal surfaces in \({\mathbb {L}}^3\) . In this paper, we investigate reflection principles for zero mean curvature surfaces in \({\mathbb {I}}^3\) as with the above surfaces in \({\mathbb {E}}^3\) and \({\mathbb {L}}^3\) . In particular, we show a reflection principle for isotropic line segments on such zero mean curvature surfaces in \({\mathbb {I}}^3\) , along which the induced metrics become singular.

  • Middle Bruck Loops and the Total Multiplication Group

    • Free pre-print version: Loading...

      Abstract: Let Q be a loop. The mappings \(x\mapsto ax\) , \(x\mapsto xa\) and \(x\mapsto a/x\) are denoted by \(L_a\) , \(R_a\) and \(D_a\) , respectively. The loop is said to be middle Bruck if for all \(a,b \in Q\) there exists \(c\in Q\) such that \(D_aD_bD_a = D_c\) . The right inverse of Q is the loop with operation \(x/(y\backslash 1)\) . It is proved that Q is middle Bruck if and only if the right inverse of Q is left Bruck (i.e., a left Bol loop in which \((xy)^{-1}= x^{-1}y^{-1}\) ). Middle Bruck loops are characterized in group theoretic language as transversals T to \(H\le G\) such that \(\langle T \rangle = G\) , \(T^G =T\) and \(t^2=1\) for each \(t\in T\) . Other results include the fact that if Q is a finite loop, then the total multiplication group \(\langle L_a,R_a,D_a; a\in Q\rangle \) is nilpotent if and only if Q is a centrally nilpotent 2-loop, and the fact that total multiplication groups of paratopic loops are isomorphic.

  • An Analytic Representation of the Second Symmetric Standard Elliptic
           Integral in Terms of Elementary Functions

    • Free pre-print version: Loading...

      Abstract: We derive new convergent expansions of the symmetric standard elliptic integral \(R_D(x,y,z)\) , for \(x, y,z\in {\mathbb {C}}{\setminus }(-\infty ,0]\) , in terms of elementary functions. The expansions hold uniformly for large and small values of one of the three variables x, y or z (with the other two fixed). We proceed by considering a more general parametric integral from which \(R_D(x,y,z)\) is a particular case. It turns out that this parametric integral is an integral representation of the Appell function \(F_1(a;b,c;a+1;x,y)\) . Therefore, as a byproduct, we deduce convergent expansions of \(F_1(a;b,c;a+1;x,y)\) . We also compute error bounds at any order of the approximation. Some numerical examples show the accuracy of the expansions and their uniform features.

      Abstract: We present a proof of a result which gives an upper bound for the minimal Maslov number of a displaceable n-dimensional Lagrangian submanifold in a weakly exact symplectic manifold with minimal Chern number at least n. The proof utilizes a result on the Conley-Zehnder index of a periodic orbit of the flow of a specifically constructed Floer Hamiltonian and an index relation.
