The group algebras k Q 2 n {kQ_{2^{n}}} of the generalized quaternion groups Q 2 n {Q_{2^{n}}} over fields k which contain 𝔽 2 n - 2 {\mathbb{F}_{2^{n-2}}} are deformed to separable k ( ( t ) ) {k((t))} -algebras [ k Q 2 n ] t {[kQ_{2^

Maximal connected grading classes of a finite-dimensional algebra A A are in one-to-one correspondence with Galois covering classes of A A which admit no proper Galois covering and therefore are key in computing the intrinsic fundamental group π 1 (

Chromatosomes play a fundamental role in chromatin regulation, but a detailed understanding of their structure is lacking, partially due to their complex dynamics. Using single-molecule DNA unzipping with optical tweezers, we reveal that linker histo

For every action $\phi\in\text{Hom}(G,\text{Aut}_k(K))$ of a group $G$ on a commutative ring $K$ we introduce two abelian monoids. The monoid $\text{Cliff}_k(\phi)$ consists of equivalent classes of $G$-graded Clifford system extensions of type $\phi

We suggest a cohomological framework to describe groups of I -type and involutive Yang–Baxter groups. These groups are key in the study of involutive non-degenerate set-theoretic solutions of the quantum Yang–Baxter equation. Our main tool is a l

Any simple group-grading of a finite dimensional complex algebra induces a natural family of digraphs. We prove that in a digraph without parallel edges, the number of pairs of vertices having a common in-neighbor or a common out-neighbor is at least

Families of codes such as group codes, constacyclic and skew cyclic codes, some of which independently suggested in the literature, turn out to be special instances of the general family of crossed product codes. Hamming-metric is a main feature of a

The semi-center of an artinian semisimple module-algebra over a finite group G can be described using the projective representations of G. In particular, the semi-center of the endomorphism ring of an irreducible projective representation over an alg

The problem of determining when a (classical) crossed product $T=S^f*G$ of a finite group $G$ over a discrete valuation ring $S$ is a maximal order, was answered in the 1960's for the case where $S$ is tamely ramified over the subring of invariants $
