The group is a DCI-group
István Kovács, Grigory Ryabov
We prove that the group is a DCI-group for distinct primes and , that is, two Cayley digraphs over are isomorphic if and only if their c…
Separability of Schur rings over abelian groups of odd order
Grigory Ryabov
An -ring (a Schur ring) is said to be separable with respect to a class of groups if every algebraic isomorphism from the -ring in question to an -ring over…
On separable Schur rings over abelian groups
Grigory Ryabov
A finite group is said to be weakly separable if every algebraic isomorphism between two -rings over this group is induced by a combinatorial isomorphism. In the paper we prove…
On Cayley representations of finite graphs over abelian p-groups
Grigory Ryabov
We construct a polynomial-time algorithm which given a graph finds the full set of non-equivalent Cayley representations of over the group , where…
