One-Dimensional Schrodinger Operator with a Negative Parameter and Its Applications to the Study of the Approximation Numbers of a Singular Hyperbolic Operator
(Faculty of Sciences and Mathematics, 2018)In this paper we use the one-dimensional Schrodinger operator with a negative parameter to the ¨ study of the approximation numbers of a hyperbolic type singular operator. Estimates for the distribution function of the approximation numbers are obtained.2024-12-18 -
Creating and Using Mobile Physics and Mathematics Applications in the Learning Process as One of Teaching Methods to Increase the Quality of Student’s Knowledge
(EURASIA Journal of Mathematics, Science and Technology Education, 2018)The purpose of the study is to create and use a simple, but very effective mobile application available for use during the learning process, as well as for student’s independent work after university hours. We have used the X code integrated development environment, developed by Apple for iPhone and iPad, in order to create the application. Our mobile application was used ...2024-12-17 -

CONCURRENTLY CONTROLLED GRAMMARS
(Kybernetika, 2018)This paper introduces a new variant of Petri net controlled grammars, namely a concurrently controlled grammar, where the control over the application of the productions of a grammar is realized by a Petri net with different parallel firing strategies. The generative capacity of these grammars is investigated with respect to transition labeling strategies, definitions of ...2024-12-17 -
On the Feasibility of Interference Alignment in Compounded MIMO Broadcast Channels With Antenna Correlation and Mixed User Classes
(IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY, 2018)This paper presents a generalized closed-form beamforming technique that can achieve the maximum degrees of freedom in compounded multiple-input multiple-output (MIMO) broadcast channels with mixed classes of multiple-antenna users. The contribution is first described within the context of a three-cell network and later extended to the general multicell scenario where we ...2024-12-18 -

Kernel oper ernel operators and their boundedness fr ors and their boundedness from weighted Sobole om weighted Sobolev space to weighted Lebesgue space
(Turkish Journal of Mathematics, 2019)In this paper, for a wide class of integral operators, we consider the problem of their boundedness from a weighted Sobolev space to a weighted Lebesgue space. The crucial step in the proof of the main result is to use the equivalence of the basic inequality and certain Hardy-type inequality, so we first state and prove this equivalence.2024-12-18 -
About one approach to solving the inverse problem for parabolic equation
(Vestnik of Saint Petersburg University. Applied Mathematics. Computer Science. Control Processes, 2019)Consider the problem of determining the coefficients in the differential equation of parabolic types and boundary conditions on the known sections of the solutions of the initial-boundary value problem. Used spectral approach based on spectral properties of the elliptic operator of the initial-boundary value problem and the methods of solving the inverse spectral problem of ...2024-12-13 -

Linearization of automorphisms and triangulation of derivations of free algebras of rank 2
(Siberian Electronic Mathematical Reports, 2019)We define a class of ◦-varieties of algebras and prove that the tame automorphism group of a free algebra of rank two of any ◦-variety of algebras over a field admits an amalgamated free product structure. In particular, the automorphism group of a free right-symmetric algebra of rank two admits an amalgamated free product structure. Using this structure, we prove that any ...2024-12-25 -
Information Security Risk Assessment in Critical Infrastructure: A Hybrid MCDM Approach
(INFORMATICA, 2019)The risk analysis has always been one of the essential procedures for any areas. The majority of security incidents occur because of ignoring risks or their inaccurate assessment. It is especially dangerous for critical infrastructures. Thus, the article is devoted to the description of the developed model of risk assessment for the essential infrastructures. The goal of the ...2024-12-18 -

Some Fourier inequalities for orthogonal systems in Lorentz–Zygmund spaces
(Journal of Inequalities and Applications, 2019)A number of classical inequalities and convergence results related to Fourier coefficients with respect to unbounded orthogonal systems are generalized and complemented. All results are given in the case of Lorentz–Zygmund spaces.2024-12-25 -
EXISTENCE AND MAXIMAL REGULARITY OF SOLUTIONS IN L2(R 2 ) FOR A HYPERBOLIC TYPE DIFFERENTIAL EQUATION WITH QUICKLY GROWING COEFFICIENTS
(EURASIAN MATHEMATICAL JOURNAL, 2020)In this paper the problem of the existence of solutions is studied for a hyperbolic type differential equation defined in an unbounded domain. The problem of the smoothness of solutions is also considered here. Such problems are of particular interest when the coefficients are unbounded. The novelty of the work is that the weighted coercive estimate is obtained for the solutions ...2024-12-18
