Feedback equivalence of convolutional codes over finite rings
Open Mathematics, 2017 The approach to convolutional codes from the linear systems point of view provides us with effective tools in order to construct convolutional codes with adequate properties that let us use them in many applications.

Finite Generation of Cox Rings
Notices of the American Mathematical Society, 2022 We discuss questions such as: When are Cox rings polynomial rings? When do two algebraic varieties have isomorphic Cox rings? The second part of the article is devoted to the question of the finite generation of the Cox ring.

Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Some conditions for finiteness and commutativity of rings
International Journal of Mathematics and Mathematical Sciences, 1990 We present several new sufficient conditions for a ring to be finite; we give two conditions which for periodic rings R imply that R must be either finite or commutative; and we study commutativity in rings with only finitely many non-central subrings.

γ-Dual Codes over Finite Commutative Chain Rings
AxiomsIn this article, the notion of γ-dual codes over finite chain rings is introduced as an extension of dual codes over finite chain rings. Various characteristics and properties of γ-dual codes over finite chain rings are explored.

The Gilbert-Varshamov Bound for Stabilizer Codes Over
IEEE Access, 2018 Quantum codes over finite rings have received a great deal of attention in recent years. Compared with quantum codes over finite fields, a notable advantage of quantum codes over finite rings is that they can adapt to quantum physical systems of ...
