Computing Higher Frobenius-schur Indicators in Fusion Categories Constructed from Inclusions of Finite Groups
We consider a subclass of the class of group-theoretical fusion categories: To every finite group G and subgroup H one can associate the category of G-graded vector spaces with a two-sided H-action compatible with the grading. We derive a formula that computes higher Frobenius-Schur indicators for the objects in such a category using the combinatorics and representation theory of the groups inv...
متن کاملCOMPUTING THE PRODUCTS OF CONJUGACY CLASSES FOR SPECIFIC FINITE GROUPS
Suppose $G$ is a finite group, $A$ and $B$ are conjugacy classes of $G$ and $eta(AB)$ denotes the number of conjugacy classes contained in $AB$. The set of all $eta(AB)$ such that $A, B$ run over conjugacy classes of $G$ is denoted by $eta(G)$.The aim of this paper is to compute $eta(G)$, $G in { D_{2n}, T_{4n}, U_{6n}, V_{8n}, SD_{8n}}$ or $G$ is a decomposable group of order $2pq$, a group of...
متن کاملOn the automorphisms of designs constructed from finite simple groups
Here we study the automorphism groups of 1-designs constructed from finite nonabelian simple groups by using two methods presented in Moori (Information Security, Coding Theory and Related Combinatorics, 2011) [9]. We obtain some general results for both and improve one of these methods. In an application to the sporadic Mathieu groups Mn, we are able to retrieve the Steiner systems S(t, t+ 3, ...
متن کاملHigher Frobenius-schur Indicators for Pivotal Categories
We define higher Frobenius-Schur indicators for objects in linear pivotal monoidal categories. We prove that they are category invariants, and take values in the cyclotomic integers. We also define a family of natural endomorphisms of the identity endofunctor on a k-linear semisimple rigid monoidal category, which we call the Frobenius-Schur endomorphisms. For a k-linear semisimple pivotal mono...
متن کاملOn the Exponent of Tensor Categories Coming from Finite Groups
We describe the exponent of a group-theoretical fusion category C = C(G,ω, F, α) associated to a finite group G in terms of group cohomology. We show that the exponent of C divides both e(ω) expG and (expG), where e(ω) is the cohomological order of the 3-cocycle ω. In particular exp C divides (dim C).
