Mathematics of Digital Communications: From Finite Fields to Group Rings and Noncommutative Algebra

Iranian Journal of Science and Technology, Transactions A: Science, 2020
In this paper, we present some recent instances of applying algebraic tools from different categories, in the design of digital communications systems. More specifically, we present a structure based on the elements of a group ring for constructing and encoding QC-LDPC codes.

Irrelation of Mathematical and Functional Aspects of Descriptive Image Algebras with One Ring Operations Interpretability

, 2019
The study is continued investigation of mathematical and functional/physical interpretation of image analysis and processing operations used as sets of operations (ring elements) in descriptive image algebras (DIA) with one ring. The main result is the determination and characterization of interpretation domains of DIA operations: image algebras that ...

Компактификации пространства $\mathcal M_{0,n}$, связанные с самодвойственными по Александеру комплексами: кольца Чжоу, $\psi $-классы и числа пересечения

Труды Математического института имени В. А. Стеклова, 2019
С каждым самодвойственным по Александеру симплициальным комплексом связана компактификация пространства $\mathcal M_{0,n}$, называемая ASD-компактификацией, которая является гладким алгебраическим многообразием. ASD-компактификации включают в себя (помимо других) пространства многоугольников, или конфигурационные пространства шарнирных многоугольников.
