Journal of Algebra, 2009 Let \(G\) be a finite group, \(F\) a field, and \(Z\) a commutative central simple \(G\)-algebra. In this paper the author introduces the Brauer-Clifford group \(\text{BrCliff}(G,Z)\). This group consists of certain equivalence classes of central simple \(G\)-algebras, and the product is associated with the tensor product of algebras.

Morita equivalence of certain crossed products [PDF]
Categories and General Algebraic Structures with Applications, 2023 We introduce an alternative criterion for Morita equivalence over graded tensor categories using equivariant centers and equivariantizations. While Morita equivalence has been extensively studied in the context of fusion categories, primarily through the

Brauer groups of moduli of hyperelliptic curves via cohomological invariants
Forum of Mathematics, Sigma, 2021 Using the theory of cohomological invariants for algebraic stacks, we compute the Brauer group of the moduli stack of hyperelliptic curves ${\mathcal {H}}_g$ over any field of characteristic $0$.

THE BRAUER GROUP OF THE DIHEDRAL GROUP [PDF]
Glasgow Mathematical Journal, 2004 Let $p^m$ be a power of a prime number $p$, $\mathbb{Dacute;_{p^m}$ be the dihedral group of order $2p^m$ and $k$ be a field where $p$ is invertible and containing a primitive $2p^m$-th root of unity. The aim of this paper is computing the Brauer group $BM(k,\mathbb{D}_{p^m},R_z)$ of the group Hopf algebra of $\mathbb{D}_{p^m}$ with respect to the ...

The equivariant Brauer group of a group [PDF]
Proceedings of the American Mathematical Society, 2005 We consider the Brauer group ${\rm BM}'(k,G)$ of a group $G$ (finite or infinite) over a commutative ring $k$ with identity. A split exact sequence $$1\longrightarrow {\rm Br}'(k)\longrightarrow {\rm BM}'(k,G)\longrightarrow {\rm Gal}(k,G) \longrightarrow 1$$ is obtained. This generalizes the Fröhlich-Wall exact sequence from the case of a field to the

Molecular Analysis of Parasitoid Flies Tachinidae
RUDN Journal of Agronomy and Animal Industries, 2022 The parasitoids from Tachinidae family have important role in biological control; nevertheless, the phylogenetic relationships of supra genera groups are poorly studied. Here, we present phylogenetic analyses of the family based on molecular data.

Irreducible Characters with Cyclic Anchor Group
Axioms, 2023 We consider G to be a finite group and p as a prime number. We fix ψ to be an irreducible character of G with its restriction to all p-regular elements of G and ψ0 to be an irreducible Brauer character.

Spaces of states of the two-dimensional $O(n)$ and Potts models
SciPost Physics, 2023 We determine the spaces of states of the two-dimensional $O(n)$ and $Q$-state Potts models with generic parameters $n,Q\in \mathbb{C}$ as representations of their known symmetry algebras.

Forum of Mathematics, Sigma, 2020 There is an error in the statement and proof of [VAV17, Proposition 5.1] that affects the statements of [VAV17, Corollaries 5.2 and 5.3]. In this note, we correct the statement of [VAV17, Proposition 5.1] and explain how to rectify subsequent statements.

A Review of Matrix SIR Arino Epidemic Models
Mathematics, 2021 Many of the models used nowadays in mathematical epidemiology, in particular in COVID-19 research, belong to a certain subclass of compartmental models whose classes may be divided into three “(x,y,z)” groups, which we will call respectively “susceptible/
