On the structure of the centralizer of a braid [PDF]
, 2003 The mixed braid groups are the subgroups of Artin braid groups whose elements preserve a given partition of the base points. We prove that the centralizer of any braid can be expressed in terms of semidirect and direct products of mixed braid groups ...

A reduction principle for Fourier coefficients of automorphic forms [PDF]
, 2020 In this paper we analyze a general class of Fourier coefficients of automorphic forms on reductive adelic groups $\mathbf{G}(\mathbb{A}_\mathbb{K})$ and their covers.

On a Functional Equation Related to Two-Sided Centralizers
Annales Mathematicae Silesianae, 2018 The main aim of this manuscript is to prove the following result. Let n > 2 be a fixed integer and R be a k-torsion free semiprime ring with identity, where k ∈ {2, n - 1, n}.

Centralizers of the infinite symmetric group [PDF]
, 2013 We review and introduce several approaches to the study of centralizer algebras of the infinite symmetric group $S_\infty$. Our study is led by the double commutant relationships between finite symmetric groups and partition algebras; each approach ...

On Nichols algebras over SL(2,Fq) and GL(2,Fq) [PDF]
, 2007 We compute necessary conditions on Yetter-Drinfeld modules over the groups SL(2,Fq) and GL(2,Fq) to generate finite dimensional Nichols algebras.

Algorithmic aspects of branched coverings [PDF]
, 2017 This is the announcement, and the long summary, of a series of articles on the algorithmic study of Thurston maps. We describe branched coverings of the sphere in terms of group-theoretical objects called bisets, and develop a theory of decompositions of

Centralizer construction of the Yangian of the queer Lie superalgebra [PDF]
, 2004 Consider the complex matrix Lie superalgebra \( \mathfrak{g}\mathfrak{l}_{\left. N \right|N} \) with the standard generators E ij where i, j = ±1, . . . , ± N. Define an involutive automorphism η of \( \mathfrak{g}\mathfrak{l}_{\left. N \right|N} \) by η(

The zero-level centralizer in endomorphism algebras [PDF]
Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 2011 For an endomorphism φ ∈ EndR(M) of a left R-module RM, we investigate the structure and the polynomial identities of the zero-level centralizer Cen0(φ) and the factor Cen(φ)/Cen0(φ). A double zero-centralizer theorem for Cen0(Cen0(φ)) is also formulated.
