Equivariant dimensions of groups with operators
Mark Grant, Ehud Meir, Irakli Patchkoria
Let be a group equipped with an action of a second group by automorphisms. We define the equivariant cohomological dimension , the equivariant geometric dime…
On isotypic decompositions for non-semisimple Hopf algebras
Vincent Koppen, Ehud Meir, Christoph Schweigert
In this paper we study the isotypic decomposition of the regular module of a finite-dimensional Hopf algebra over an algebraically closed field of characteristic zero. For a semisi…
Invariant rings and representations of the symmetric groups
Ehud Meir, with an appendix by Dejan Govc
In this paper we study invariant rings arising in the study of finite dimensional algebraic structures. The rings we encounter are graded rings of the form where is a…
Geometric perspective on Nichols algebras
Ehud Meir
We formulate the generation of finite dimensional pointed Hopf algebras by group-like elements and skew-primitives in geometric terms. This is done through a more general study of…
