  • BISECTORS IN VECTOR GROUPS OVER INTEGERS
    • Authors: SHENG BAU; YIMING LEI
      Pages: 353 - 361
      Abstract: We present an example of an isometric subspace of a metric space that has a greater metric dimension. We also show that the metric spaces of vector groups over the integers, defined by the generating set of unit vectors, cannot be resolved by a finite set. Bisectors in the spaces of vector groups, defined by the generating set consisting of unit vectors, are completely determined.

  • APPLICATIONS OF LERCH’S THEOREM TO PERMUTATIONS OF QUADRATIC
           RESIDUES
    • Authors: LI-YUAN WANG; HAI-LIANG WU
      Pages: 362 - 371
      Abstract: Let $n$ be a positive integer and $a$ an integer prime to $n$ . Multiplication by $a$ induces a permutation over $\mathbb{Z}/n\mathbb{Z}=\{\overline{0},\overline{1},\ldots ,\overline{n-1}\}$ . Lerch’s theorem gives the sign of this permutation. We explore some applications of Lerch’s result to permutation problems involving quadratic residues modulo $p$ and confirm some conjectures posed by Sun [‘Quadratic residues and related permutations and identities’, Preprint, 2018, arXiv:1809.07766]. We also study permutations involving arbitrary $k$ th power residues modulo $p$ and primitive roots modulo a power of  $p$ .

    • Authors: PIETER MOREE; MIN SHA
      Pages: 388 - 394
      Abstract: Let $p$ be a prime. If an integer $g$ generates a subgroup of index $t$ in $(\mathbb{Z}/p\mathbb{Z})^{\ast },$ then we say that $g$ is a $t$ -near primitive root modulo $p$ . We point out the easy result that each coprime residue class contains a subset of primes $p$ of positive natural density which do not have $g$ as a $t$ -near primitive root and we prove a more difficult variant.

  • ON COMPLEX HOMOGENEOUS SINGULARITIES

      Abstract: We study the singularity at the origin of $\mathbb{C}^{n+1}$ of an arbitrary homogeneous polynomial in $n+1$ variables with complex coefficients, by investigating the monodromy characteristic polynomials $\unicode[STIX]{x1D6E5}_{l}(t)$ as well as the relation between the monodromy zeta function and the Hodge spectrum of the singularity. In the case $n=2$ , we give a description of $\unicode[STIX]{x1D6E5}_{C}(t)=\unicode[STIX]{x1D6E5}_{1}(t)$ in terms of the multiplier ideal.

    • Authors: VU THE KHOI
      Pages: 440 - 445
      Abstract: In this paper, we study the probability distribution of the word map $w(x_{1},x_{2},\ldots ,x_{k})=x_{1}^{n_{1}}x_{2}^{n_{2}}\cdots x_{k}^{n_{k}}$ in a compact Lie group. We show that the probability distribution can be represented as an infinite series. Moreover, in the case of the Lie group $\text{SU}(2)$ , our computations give a nice convergent series for the probability distribution.

      Abstract: For $G$ a finite non-Abelian group we write $c(G)$ for the probability that two randomly chosen elements commute and $k(G)$ for the largest integer such that any $k(G)$ -colouring of $G$ is guaranteed to contain a monochromatic quadruple $(x,y,xy,yx)$ with $xy\neq yx$ . We show that $c(G)\rightarrow 0$ if and only if $k(G)\rightarrow \infty$ .

  • A REMARK ON THE SEPARABLE QUOTIENT PROBLEM FOR TOPOLOGICAL GROUPS
    • Authors: SIDNEY A. MORRIS
      Pages: 453 - 457
      Abstract: The Banach–Mazur separable quotient problem asks whether every infinite-dimensional Banach space $B$ has a quotient space that is an infinite-dimensional separable Banach space. The question has remained open for over 80 years, although an affirmative answer is known in special cases such as when $B$ is reflexive or even a dual of a Banach space. Very recently, it has been shown to be true for dual-like spaces. An analogous problem for topological groups is: Does every infinite-dimensional (in the topological sense) connected (Hausdorff) topological group $G$ have a quotient topological group that is infinite dimensional and metrisable? While this is known to be true if $G$ is the underlying topological group of an infinite-dimensional Banach space, it is shown here to be false even if $G$ is the underlying topological group of an infinite-dimensional locally convex space. Indeed, it is shown that the free topological vector space on any countably infinite $k_{\unicode[STIX]{x1D714}}$ -space is an infinite-dimensional toplogical vector space which does not have any quotient topological group that is infinite dimensional and metrisable. By contrast, the Graev free abelian topological group and the Graev free topological group on any infinite connected Tychonoff space, both of which are connected topological groups, are shown here to have the tubby torus $\mathbb{T}^{\unicode[STIX]{x1D714}}$ , which is an infinite-dimensional metrisable group, as a quotient group.

  • ESTIMATES OF THE SECOND DERIVATIVE OF BOUNDED ANALYTIC FUNCTIONS
    • Authors: GANGQIANG CHEN
      Pages: 458 - 469
      Abstract: Assume a point $z$ lies in the open unit disk $\mathbb{D}$ of the complex plane $\mathbb{C}$ and $f$ is an analytic self-map of $\mathbb{D}$ fixing 0. Then Schwarz’s lemma gives $|f(z)|\leq |z|$ , and Dieudonné’s lemma asserts that $|f^{\prime }(z)|\leq \min \{1,(1+|z|^{2})/(4|z|(1-|z|^{2}))\}$ . We prove a sharp upper bound for $|f^{\prime \prime }(z)|$ depending only on  $|z|$ .

  • ESSENTIAL AMENABILITY OF DUAL BANACH ALGEBRAS
    • Authors: MOHSEN ZIAMANESH; BEHROUZ SHOJAEE, AMIN MAHMOODI
      Pages: 479 - 488
      Abstract: We show that an essentially amenable Banach algebra need not have an approximate identity. This answers a question posed by Ghahramani and Loy [‘Generalized notions of amenability’, J. Funct. Anal.  208 (2004), 229–260]. Essentially Connes-amenable dual Banach algebras are introduced and studied.

  • LIPSCHITZ-TYPE INEQUALITIES FOR ANALYTIC FUNCTIONS IN BANACH ALGEBRAS
    • Authors: SILVESTRU SEVER DRAGOMIR
      Pages: 489 - 497
      Abstract: In this paper we provide some bounds for the quantity $\Vert f(y)-f(x)\Vert$ , where $f:D\rightarrow \mathbb{C}$ is an analytic function on the domain $D\subset \mathbb{C}$ and $x$ , $y\in {\mathcal{B}}$ , a Banach algebra, with the spectra $\unicode[STIX]{x1D70E}(x)$ , $\unicode[STIX]{x1D70E}(y)\subset D$ . Applications for the exponential and logarithmic functions on the Banach algebra ${\mathcal{B}}$ are also given.

      Abstract: Let ${\mathcal{D}}$ be a Schauder decomposition on some Banach space $X$ . We prove that if ${\mathcal{D}}$ is not $R$ -Schauder, then there exists a Ritt operator $T\in B(X)$ which is a multiplier with respect to ${\mathcal{D}}$ such that the set $\{T^{n}:n\geq 0\}$ is not $R$ -bounded. Likewise, we prove that there exists a bounded sectorial operator $A$ of type $0$ on $X$ which is a multiplier with respect to

      Abstract: The Lusternik–Schnirelmann category cat and topological complexity TC are related homotopy invariants. The topological complexity TC has applications to the robot motion planning problem. We calculate the Lusternik–Schnirelmann category and topological complexity of the ordered configuration space of two distinct points in the product $G\times \mathbb{R}^{n}$ and apply the results to the planar and spatial motion of two rigid bodies in $\mathbb{R}^{2}$ and $\mathbb{R}^{3}$ respectively.
