Abstract: We give a presentation of the centralizer algebras for tensor products of spinor representations of quantum groups via generators and relations. In the even-dimensional case, this can be des...
The centralizer of an $I$-matrix in $M_2(R/I)$, $R$ a UFD
Centralizer I-matrix matrix ring unique factorization domain principal ideal domain

Abstract: The concept of an $I$-matrix in the full $2\times 2$ matrix ring $M_2(R/I)$, where $R$ is an arbitrary UFD and $I$ is a nonzero ideal in $R$, is introduced. We obtain a concrete description ...
Centralizer of the elementary subgroup of an isotropic reductive group
Centralizer of the elementary subgroup isotropic reductive group

Let R be a commutative ring with 1, and let G be an isotropic reductive algebraic group over R. In [5] Victor Petrov and the second author introduced a notion of an elementary subgroup E(R) of the gro...

Modular Centralizer Algebras p-Groups

We study the Loewy structure of the centralizer algebra kP^Q for P a p-group with subgroup Q and k a field of characteristic p. Here kP^Q is a special type of Hecke algebra. The main tool we employ i...

We show that there exists a non-linear, locally finite, simple group such that the centralizer of every non-trivial element is (locally solvable)-by-finite.
