On automorphism groups of Toeplitz subshifts [PDF]
, 2017 In this article we study automorphisms of Toeplitz subshifts. Such groups are abelian and any finitely generated torsion subgroup is finite and cyclic.

Automorphism Ensemble Decoding of Reed–Muller Codes [PDF]
IEEE Transactions on Communications, 2020 Reed–Muller (RM) codes are known for their good maximum likelihood (ML) performance in the short block-length regime. Despite being one of the oldest classes of channel codes, finding a low complexity soft-input decoding scheme is still an open problem ...

Rigid automorphisms of linking systems
Forum of Mathematics, Sigma, 2021 A rigid automorphism of a linking system is an automorphism that restricts to the identity on the Sylow subgroup. A rigid inner automorphism is conjugation by an element in the center of the Sylow subgroup.

The Stabilized Automorphism Group of a Subshift [PDF]
International mathematics research notices, 2020 For a mixing shift of finite type, the associated automorphism group has a rich algebraic structure, and yet we have few criteria to distinguish when two such groups are isomorphic.

Automorphisms and Inner Automorphisms [PDF]
Journal of Mathematics, 2016 LetKbe a field of characteristic not2and letA=A0+A1be central simple superalgebra overK, and let⁎be superinvolution onA. Our main purpose is to classify the group of automorphisms and inner automorphisms of(A,⁎)(i.e., commuting with⁎) by using the classical theorem of Skolem-Noether.

On a relation between GAG codes and AG codes
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023 In this paper, we first give a relationship between generalized algebraic geometry codes (GAG codes) and algebraic geometry codes (AG codes). More precisely, we show that a GAG code is contained (up to isomorphism) in a suitable AG code.

Transitive Deficiency One Parallelisms of PG(3, 7)
Mathematics, 2023 Consider the n-dimensional projective space PG(n,q) over a finite field with q elements. A spread in PG(n,q) is a set of lines which partition the point set. A parallelism is a partition of the set of lines by spreads.
