The automorphism group of the zero-divisor digraph of matrices over an antiring

David Dolžan, Gabriel Verret

We determine the automorphism group of the zero-divisor digraph of the semiring of matrices over an antinegative commutative semiring with a finite number of zero-divisors.

Skew product groups for monolithic groups

Martin Bachratý, Marston Conder, Gabriel Verret

Skew morphisms, which generalise automorphisms for groups, provide a fundamental tool for the study of regular Cayley maps and, more generally, for finite groups with a complementa…

Arc-transitive graphs of valency twice a prime admit a semiregular automorphism

Michael Giudici, Gabriel Verret

We prove that every finite arc-transitive graph of valency twice a prime admits a nontrivial semiregular automorphism, that is, a non-identity automorphism whose cycles all have th…
