  • On Dirichlet problem

    • Free pre-print version: Loading...

      Abstract: During almost two centuries after the Gauss’ formulation of the Dirichlet problem for Laplace equation, many famous mathematicians devoted their studies to this subject and to its various generalizations. Many interesting and important results have been obtained, which become already classical ones. Our paper is an extended presentation of the author’s talk on the international conference dedicate to the century of V. S. Vladimirov birthday. Its main content is the review of the results in that direction, including the proves of new statements and discussion of unsolved problems. Our goal is to convince readers that, in this “principal” problem of mathematical physics, we know far from everything even about the case of linear equation. There are many interesting and important unsolved problems in that direction.

    • Free pre-print version: Loading...

      Abstract: A model Helmholtz equation with a localized right-hand side is considered. When writing asymptotics of a solution satisfying the limit absorption principle, a Lagrangian surface naturally appears that has a logarithmic singularity at one point. Because of this singularity, the solution is localized not only in a neighborhood of the projection of the Lagrangian surface onto the coordinate space but also in a neighborhood of a certain ray “escaping” from the Lagrangian surface and going into the region forbidden in the classical approximation.

  • On qualitative properties of the solution of a boundary value problem for
           a system of nonlinear integral equations

    • Free pre-print version: Loading...

      Abstract: For a system of nonlinear integral equations on the semiaxis, we study a boundary value problem whose matrix kernel has unit spectral radius. This boundary value problem has applications in various areas of physics and biology. In particular, such problems arise in the dynamical theory of \(p\) -adic strings for the scalar field of tachyons, in the mathematical theory of spread of epidemic diseases, in the kinetic theory of gases, and in the theory of radiative transfer. The questions of the existence, absence, and uniqueness of a nontrivial solution of this boundary value problem are discussed. In particular, it is proved that a boundary value problem with a zero boundary conditions at infinity has only a trivial solution in the class of nonnegative and bounded functions. It is also proved that if at least one of the values at infinity is positive, then this problem has a convex nontrivial nonnegative bounded and continuous solution. At the end of this paper, examples of the matrix kernel and nonlinearity are provided that satisfy all the conditions of the proved theorems.

  • Ternary $$Z_3$$ -symmetric algebra and generalized quantum oscillators

    • Free pre-print version: Loading...

      Abstract: We present a generalized version of a quantum oscillator described by means of a ternary Heisenberg algebra. The model leads to a sixth-order Hamiltonian whose energy levels can be discretized using the Bohr–Sommerfeld quantization procedure. We note the similarity with the \(Z_3\) -extended version of Dirac’s equation applied to quark color dynamics, which also leads to sixth-order field equations. The paper also contains a comprehensive guide to \(Z_3\) -graded structures, including ternary algebras, which form a mathematical basis for the proposed generalization. The symmetry properties of the model are also discussed.

  • On the quarkyonic phase in the holographic approach

    • Free pre-print version: Loading...

      Abstract: We study the problem of the existence of the quarkyonic phase in quantum chromodynamics. This phase can exists under certain conditions in quantum chromodynamics along with the phase of free quarks and the confinement phase. As is known, the confinement phase is characterized by the presence of a linear potential between quarks, and the quarks are confined to one hadron (meson or baryon). A linear potential between quarks also exists in the quarkyonic phase; however, it is not so strong to confine quarks inside one hadron. The characteristics of the quarkyonic phase, as well as the confinement phase, can be calculated in quantum chromodynamics only in a nonperturbative framework. We interpret the previously obtained results of Wilson loop calculations in the holographic approach in terms of a phase transition to the quarkyonic phase.

  • The structure of quantum corrections and exact results in supersymmetric
           theories from the higher covariant derivative regularization

    • Free pre-print version: Loading...

      Abstract: We review some recent results of the studies of quantum corrections in supersymmetric theories derived using Slavnov’s higher covariant derivative regularization. In particular, we demonstrate that the \(\beta\) -function of \(\mathcal{N}=1\) supersymmetric theories is related to the anomalous dimensions of matter superfields by the NSVZ relation if the theory is regularized by higher covariant derivatives and the renormalization group functions are defined in terms of the bare couplings, because the corresponding loop corrections are given by integrals of double total derivatives in the momentum space. For the standard renormalization-group functions, we show that an all-loop NSVZ renormalization scheme is given by the HD \(\,+\,\) MSL renormalization prescription when the higher covariant derivative regularization is supplemented by minimal subtractions of logarithms. Applications of these results to the precise calculations in various supersymmetric theories are briefly described.

  • Comments on a 4-derivative scalar theory in 4 dimensions

    • Free pre-print version: Loading...

      Abstract: We review and elaborate on some aspects of the classically scale-invariant renormalizable \(4\) -derivative scalar theory \(L=\phi\,\partial^4\phi+g(\partial\phi)^4\) . Similar models appear, e.g., in the context of conformal supergravity or in the description of the crystalline phase of membranes. Considering this theory in Minkowski signature, we suggest how to define Poincaré-invariant scattering amplitudes by assuming that only massless oscillating (nongrowing) modes appear as external states. In such shift-symmetric interacting theory, there are no IR divergences despite the presence of \(1/q^4\) internal propagators. We discuss how nonunitarity of this theory manifests itself at the level of the one-loop massless scattering amplitude.

  • Quantum corrections to the effective potential in nonrenormalizable
           theories

    • Free pre-print version: Loading...

      Abstract: For the effective potential in the leading logarithmic approximation, we construct a renormalization group equation that holds for arbitrary scalar field theories, including nonrenormalizable ones, in four dimensions. This equation reduces to the usual renormalization group equation with a one-loop beta-function in the renormalizable case. The solution of this equation sums up the leading logarithmic contributions in the field in all orders of the perturbation theory. This is a nonlinear second-order partial differential equation in general, but it can be reduced to an ordinary one in some cases. In specific examples, we propose a numerical solution of this equation and construct the effective potential in the leading logarithmic approximation. We consider two examples as an illustration: a power-law potential and a cosmological potential of the \(\tan^2\phi\) type. The obtained equation in physically interesting cases opens up the possibility of studying the properties of the effective potential, the presence of additional minima, spontaneous symmetry breaking, stability of the ground state, etc.

  • Cluster variables for affine Lie–Poisson systems

    • Free pre-print version: Loading...

      Abstract: We show that having any planar (cyclic or acyclic) directed network on a disc with the only condition that all \(n_1+m\) sources are separated from all \(n_2+m\) sinks, we can construct a cluster-algebra realization of elements of an affine Lie–Poisson algebra \(R(\lambda,\mu){\stackrel{1}{T}}(\lambda){\stackrel{2}{T}}(\mu) ={\stackrel{2}{T}}(\mu){\stackrel{1}{T}}(\lambda)R(\lambda,\mu)\) with \(({n_1\times n_2})\) -matrices \(T(\lambda)\) . Upon satisfaction of some invertibility conditions, we can construct a realization of a quantum loop algebra. Having the quantum loop algebra, we can also construct a realization of the twisted Yangian algebra or of the quantum reflection equation. For each such a planar network, we can therefore construct a symplectic leaf of the corresponding infinite-dimensional algebra.

  • Novel integrability in string theory from automorphic symmetries

    • Free pre-print version: Loading...

      Abstract: We develop a technique based on the boost automorphism for finding new lattice integrable models with various dimensions of local Hilbert spaces. We initiate the method by implementing it in two-dimensional models and resolve a classification problem, which not only confirms the known vertex model solution space but also extends to the new \(\mathfrak{sl}_2\) deformed sector. A generalization of the approach to integrable string backgrounds is provided and allows finding new integrable deformations and associated \(R\) -matrices. The new integrable solutions appear to be of a nondifference or pseudo-difference form admitting \(AdS_2\) and \(AdS_3\) \(S\) -matrices as special cases (embeddings), which also includes a map of the double-deformed sigma model \(R\) -matrix. The corresponding braiding and conjugation operators of the novel models are derived. We also demonstrate implications of the obtained free-fermion analogue for \(AdS\) deformations.

  • A new stability equation for the Abelian Higgs–Kibble model with a

    • Free pre-print version: Loading...

      Abstract: We show that the dynamics of the scalar Higgs field in the Abelian Higgs–Kibble model supplemented with a dimension-6 derivative operator can be constrained at the quantum level by a certain stability equation. It holds in the Landau gauge and is derived within the recently proposed extended field formalism, where the physical scalar is described by a gauge-invariant field variable. Physical implications of the stability equation are discussed.
