On WL-rank and WL-dimension of some Deza circulant graphs

Ravil Bildanov, Viktor Panshin, Grigory Ryabov

The WL-rank of a digraph $Γ$ is defined to be the rank of the coherent configuration of $Γ$ . The WL-dimension of $Γ$ is defined to be the smallest positive integer $m$ for which $Γ…

The Weisfeiler-Leman dimension of chordal bipartite graphs without bipartite claw

Ilia Ponomarenko, Grigory Ryabov

A graph $X$ is said to be chordal bipartite if it is bipartite and contains no induced cycle of length at least $6$ . It is proved that if $X$ does not contain bipartite claw as an…

The Cayley isomorphism property for the group $C_{2}^{5} \times C_{p}$

Grigory Ryabov

A finite group $G$ is called a DCI-group if two Cayley digraphs over $G$ are isomorphic if and only if their connection sets are conjugate by a group automorphism. We prove that th…

The Cayley isomorphism property for the group $C_{4} \times C_{p}^{2}$

Grigory Ryabov

A finite group $G$ is called a DCI-group if two Cayley digraphs over $G$ are isomorphic if and only if their connection sets are conjugate by a group automorphism. We prove that th…
