Dihedral groups of square-free order are DCI-groups

István Kovács, Gábor Somlai

A finite group $G$ is a called a DCI-group if any two isomorphic Cayley digraphs of $G$ are also isomorphic via an automorphism of $G$ . If $G$ is a non-abelian generalised dihedral…

Lower bounds for mask polynomials with many cyclotomic divisors

Gergely Kiss, Izabella Łaba, Caleb Marshall +1

Given a nonempty set $A \subset N \cup {0}$ , define the mask polynomial $A (X) = \sum_{a \in A} X^{a}$ . Suppose that there are $s_1,\dots,s_k\in\nn\setminus\{1\}$ such that the…
