In this short note we prove that the finite non-abelian simple groups PSL(2,q),where q =5,7,are determined by their posets of classes of isomorphic subgroups.Se
In this paper we give necessary and sufficient conditions for a comodule magma over a weak Hopf quasigroup to have a total integral,thus extending the theories
Let G be a group,and let (→Γ)C(G) be a digraph whose vertices are the non-trivial conjugacy classes of G and there is an arc from a vertex C to a vertex C’if
We obtain a necessary condition for a strictly weakly integral generalized Tambara-Yamagami fusion category to be braided.Then we use this result to classify br
