Paragraded structures inspired by mathematical logic [PDF]

open access: yes, 2016
We use methods from mathematical logic to give new examples of paragraded structures, showing that at certain cardinals all first order structures are paragraduaded. We introduce the notion of bi-embeddability to measure when two paragraduaded structures

On nonnil-S-Noetherian and nonnil-u-S-Noetherian rings

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
Let R be a commutative ring with identity, and let S be a multiplicative subset of R. Then R is called a nonnil-S-Noetherian ring if every nonnil ideal of R is S-finite.

Algebraic structures in two-dimensional conformal field theory

open access: yes, 2023
The symmetries of two-dimensional conformal field theories (CFTs) can be formalised as chiral algebras, vertex operator algebras or nets of observable algebras. Their representation categories are abelian categories having additional structures.

Discrete mathematical model of the scattering process of E-polarized wave on a periodic impedance grating

open access: yesVisnik Harkivsʹkogo Nacionalʹnogo Universitetu im. V.N. Karazina. Cepiâ Matematika, Prikladna Matematika i Mehanika, 2019
The method of numerical modeling of wave scattering by periodic impedance grating is considered. In the case of a harmonic dependence of the field on time and the uniformity of the structure along a certain axis, the three-dimensional problem reduces to ...
