Relative genericity of controllablity and stabilizability for differential-algebraic systems
MCSS. Mathematics of Control, Signals and Systems, 2022 The present note is a successor of Ilchmann and Kirchhoff (Math Control Signals Syst 33:359–377, 2021) on generic controllability and stabilizability of linear differential-algebraic equations. We resolve the drawback that genericity is considered in the

Nuclear Physics B, 2021 In the present paper we develop the algebraic Bethe ansatz approach to the case of non-skew-symmetric gl(2)⊗gl(2)-valued Cartan-non-invariant classical r-matrices with spectral parameters. We consider the two families of these r-matrices, namely, the two

Solvers for Systems of Linear Algebraic Equations with Block-Band Matrices
Bulletin of the South Ural State University. Series "Mathematical Modelling, Programming and Computer Software", 2021 Summary: The article proposes methods for constructing fast solvers for systems of linear algebraic equations with block-band matrices. A data structure for efficient storage of such matrices in RAM and a fast algorithm for solving systems of linear equations with such matrices based on this structure are proposed.

A spectral approach for time-fractional diffusion and subdiffusion equations in a large interval
Mathematical Modelling and Analysis, 2022 In this paper, we concentrate on a class of time-fractional diffusion and subdiffusion equations. To solve the mentioned problems, we construct twodimensional Genocchi-fractional Laguerre functions (G-FLFs).

Spectral Decomposition of Gramians of Continuous Linear Systems in the Form of Hadamard Products
Mathematics, 2023 New possibilities of Gramian computation, by means of canonical transformations into diagonal, controllable, and observable canonical forms, are shown. Using such a technique, the Gramian matrices can be represented as products of the Hadamard matrices ...
