On Automorphism Groups of Finite Chain Rings [PDF]
Symmetry, 2021 A finite ring with an identity is a chain ring if its lattice of left ideals forms a unique chain. Let R be a finite chain ring with invaraints p,n,r,k,k′,m. If n=1, the automorphism group Aut(R) of R is known. The main purpose of this article is to study the structure of Aut(R) when n>1. First, we prove that Aut(R) is determined by the automorphism

Drak Is Required for Actomyosin Organization During Drosophila Cellularization
G3: Genes, Genomes, Genetics, 2016 The generation of force by actomyosin contraction is critical for a variety of cellular and developmental processes. Nonmuscle myosin II is the motor that drives actomyosin contraction, and its activity is largely regulated by phosphorylation of the ...

Electronic Notes in Discrete Mathematics, 2013 Abstract Let R be a finite chain ring. In this note we introduce R-designs with repeated blocks in the Grassmanian of all submodules over a chain ring R of given shape κ. We prove that for some sufficiently large t − ( n , k , l ) R-designs with repeated blocks do exist for all integers t , k , n with 0 t k n − t

Chain conditions on composite Hurwitz series rings
Open Mathematics, 2017 In this paper, we study chain conditions on composite Hurwitz series rings and composite Hurwitz polynomial rings. More precisely, we characterize when composite Hurwitz series rings and composite Hurwitz polynomial rings are Noetherian, S-Noetherian or ...

The Mechanics of a Chain or Ring of Spherical Magnets [PDF]
SIAM Journal on Applied Mathematics, 2013 Strong magnets, such as neodymium-iron-boron magnets, are increasingly being manufactured as spheres. Because of their dipolar characters, these spheres can easily be arranged into long chains that exhibit mechanical properties reminiscent of elastic strings or rods.

AIMS Mathematics, 2022 <abstract><p>An associative Artinian ring with an identity is a chain ring if its lattice of left (right) ideals forms a unique chain. In this article, we first prove that for every chain ring, there exists a certain finite commutative chain subring which characterizes it.

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.
