报告摘要:In this talk, we focus on the dihedral groups and dicyclic groups, and consider their corresponding integral Cayley graph. We obtain the sufficient conditions for the integrality of the distance powers $\Gamma^D$ of Cayley graph $\Gamma=X(D_{2n},S)$ (resp. $\Gamma=X(T_{4n},S)$) ($n\geq3$) and a set of nonnegative integers $D$. In particular, for a prime $p$, we show that if $\Gamma=X(D_{2p},S)$ (resp. $\Gamma=X(T_{4p},S)$) are integral, then distance powers of $\Gamma=X(D_{2p},S)$ (resp. $\Gamma=X(T_{4p},S)$) are integral Cayley graphs.
