The Image of Functor Morphing
Ehud Meir
Functor morphing provides a method to translate complex representations of automorphism groups of finite modules over finite rings to representations of automorphism groups of func…
Functor morphing and representations of automorphism groups of modules
Tyrone Crisp, Ehud Meir, Uri Onn
We introduce a strategy to study irreducible representations of automorphism groups of finite modules over local rings. We prove that these automorphism groups fit in a hierarchy t…
Invariants of r-spin TQFTs and non-semisimplicity
Nils Carqueville, Ehud Meir, Lorant Szegedy
For a positive integer r, an r-spin topological quantum field theory is a 2-dimensional TQFT with tangential structure given by the r-fold cover of SO_2 . In particular, such a TQF…
Finite-dimensional Nichols algebras of simple Yetter-Drinfeld modules (over groups) of prime dimension
I. Heckenberger, E. Meir, L. Vendramin
Over fields of characteristic zero, we determine all absolutely irreducible Yetter-Drinfeld modules over groups that have prime dimension and yield a finite-dimensional Nichols alg…
Comparison of equivariant cohomological dimensions
Mark Grant, Kevin Li, Ehud Meir +1
We compare three definitions of the equivariant cohomological dimension of a group with operators, coming from Takasu, Adamson and Bredon relative group cohomologies, giving exampl…
Invariants that are covering spaces and their Hopf algebras
Ehud Meir
In a previous paper by the author a universal ring of invariants for algebraic structures of a given type was constructed. This ring is a polynomial algebra that is generated by ce…
