A spectral approach for time-fractional diffusion and subdiffusion equations in a large interval

open access: yesMathematical 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).

Solvers for Systems of Linear Algebraic Equations with Block-Band Matrices

open access: yesBulletin 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.

Quantum symmetry algebras of spin systems related to Temperley–Lieb R-matrices [PDF]

open access: yesJournal of Mathematical Physics, 2008
A reducible representation of the Temperley–Lieb algebra is constructed on the tensor product of n-dimensional spaces. One obtains as a centralizer of this action a quantum algebra (a quasitriangular Hopf algebra) Uq with a representation ring equivalent to the representation ring of the sl2 Lie algebra.
