Clifford Theory for Cocentral Extensions
The classical Clifford correspondence for normal subgroups is considered in the more general setting of semisimple Hopf algebras. We prove that this correspondence still holds if the extension determined by the normal Hopf subalgebra is cocentral.
متن کاملClifford Theory for Association Schemes
Clifford theory of finite groups is generalized to association schemes. It shows a relation between irreducible complex characters of a scheme and a strongly normal closed subset of the scheme. The restriction of an irreducible character of a scheme to a strongly normal closed subset coniatns conjugate characters with same multiplicities. Moreover some strong relations are obtained.
متن کاملClifford theory for tensor categories
A graded tensor category over a group G will be called a strongly G-graded tensor category if every homogeneous component has at least one invertible object. Our main result is a description of the module categories over a strongly G-graded tensor category as induced from module categories over tensor subcategories associated with the subgroups of G.
متن کاملCyclic groups and elementary number theory
The story of cyclic groups is very much connected with elementary number theory (factorization, prime numbers, congruences). We prove some basic facts from “first principles,” using a few results about addition, multiplication, and order in N. One of the most basic facts is the following: Theorem 1.1 (Long division with remainder). Let n ∈ N. Then for all a ∈ Z, there exist unique integers q an...
متن کاملClifford Periodicity from Finite Groups
We deduce the periodicity 8 for the type of Pin and Spin representations of the orthogonal groups O(n) from simple combinatorial properties of the finite Clifford groups generated by the gamma matrices. We also include the case of arbitrary signature O(p, q). The changes in the type of representation can be seen as a rotation in the complex plane. The essential result is that adding a (+) dimen...
