  • Sergeev S.; Kuznetsova A. (2021)
    Mass protest movements of the early 2010s, particularly the Occupy movement, stimulated the rise of radical left organizations globally. In Southern Europe, radical left parties celebrated their first electoral successes. ...
  • Kozhevnikova L.M.; Kamaletdinov A.S. (2021)
    In this paper, we consider a certain class of anisotropic second-order elliptic equations of divergent type with variable indices of nonlinearities. We examine conditions of the solvability in the whole space ℝn, n ≥ 2. ...
  • Abyzov A.N.; Tuganbaev A.A.; Tapkin D.T.; Cong Q.T. (2021)
    This paper contains new and previously known results on modules that are close to direct projective and direct injective modules. The main results are presented with proofs.
  • Abyzov A.N.; Quynh T.C.; Tuganbaev A.A. (2021)
    The paper contains both known and new results on automorphism-invariant modules, automorphism-coinvariant modules and modules which are invariant or coinvariant with respect to idempotent endomorphisms of its hull and its ...
  • Kalimullin I.S.; Selivanov V.L.; Frolov A.N. (2021)
    In this survey, we discuss computability spectra of countable structures that provide a natural measure of non-computability of a structure. This notion is a main tool for investigating algorithmic properties of countable ...
  • Il’in S.N. (2021)
    In this paper, we present results on the homological classification of semirings for the last ten years and certain new results.
  • Frolov A.N. (2021)
    The main goal of this paper is to study algorithmic properties of countable linear orders by constructing effective presentations of these structures on the set of natural numbers. In 1991, C. Jockusch and R. Soare constructed ...
  • Skryabin S.M. (2021)
    This paper is a survey of recent works on invariants of actions of Hopf algebras. Its highlights are results on integrality of H-module PI algebras over subrings of invariant elements obtained by P. Etingof and M. Eryashkin. ...
  • Frolov A.N.; Zubkov M.V. (2021)
    In this paper, we describe the technique of extremely monotonic functions in the theory of computable linear orders. The basic definitions of extremely monotonic functions and their generalizations are given, and a number ...
  • Selivanov V.L. (2021)
    In this survey, we discuss the theory of precomplete numberings, which appear frequently in computability theory. Precomplete numberings are closely related to some versions of the fixed-point theorem having an important ...
  • Kalimullin I.S.; Faizrahmanov M.K. (2021)
    This paper is a survey of results on countable families with natural degree spectra. These results were obtained by a modification of the methodology proposed by Wechner, who first found a family of sets with the spectrum ...
  • Arslanov M.M.; Yamaleev M.M. (2021)
    In this work, we review results of the last years related to the development of the structural theory of n-c.e. Turing degrees for n > 1. We also discuss possible approaches to solution of the open problems.
  • Kozhevnikova L.M. (2021)
    For a class of second-order anisotropic elliptic equations with variable nonlinearity indices and summable right-hand sides, we consider the Dirichlet problem in arbitrary unbounded domains. We prove the existence and ...
  • Al’pin Y.A.; Bashkin I.V. (2021)
    A description of nonnegative chainable matrices, based on fully indecomposable matrices, is given. The notion of the chainable rank of a nonnegative matrix is introduced and investigated. Properties of chainable matrices ...
  • Ismagilov A.A.; Kayumova A.V.; Kayumov I.R.; Ponnusamy S. (2021)
    The paper is a review of the latest results of I. R. Kayumov and S. Ponnusamy on the Bohr inequality. An exact estimate in the strong Bohr inequality is obtained and the Bohr–Rogosinski radius for a certain class of ...
  • Bikchentaev A.M. (2021)
    In this paper, we present new properties of the space L1(M, τ) of integrable (with respect to the trace τ) operators affiliated to a semifinite von Neumann algebra M. For self-adjoint τ-measurable operators A and B, we ...
  • Avkhadiev F.G. (2021)
    Certain Hardy inequalities in domains of Euclidean space contain sharp but unreachable constants. V. G. Maz’ya and other authors used this fact to improve the corresponding inequalities by adding new integral terms. In ...
  • Solomonov V.I.; Spirina A.V.; Popov M.P.; Makarova A.S.; Nikolaev A.G.; Orlov A.N. (2021)
    In this paper, we present the findings of research on absorption spectra, reflection spectra, and luminescence spectra for a new decorative stone—rayizite, which is a mixture of antigorite, dolomite, and a small amount of ...
  • Alimov M.M.; Bazilevsky A.V.; Kornev K.G. (2021)
    The classical Plateau problem of finding minimal surfaces supported by two noncircular coaxial rings is studied theoretically and experimentally. Using a fluid dynamics analogy, we generalize the classical catenoid solution ...
  • Kuznetsova A.A.; Chachkov D.V.; Belogorlova N.A.; Kuimov V.A.; Malysheva S.F.; Vereshchagina Y.A. (2021)
    Abstract: The polarity and structure of tri(1- or 2-naphthyl)phosphines and their chalcogenides were determined by the methods of dipole moments, IR spectroscopy, and DFT quantum-chemical calculations at the B3PW91/6-311++G(df,p) ...
