On the automorphism group of direct product of digraphs

Guang Rao, Yu Wang, Binzhou Xia

Determining the conditions under which the direct product of graphs $G$ and $H$ satisfies $Aut (G \times H) = Aut (G) \times Aut (H)$ has been a problem of consi…

Hulls and sums of separable constacyclic codes over $F_{q} \times (F_{q} + v F_{q})$ and new quantum codes

Yu Qian, Yu Wang, Liqi Wang

We establish the generator polynomials of the Euclidean and Hermitian duals of separable constacyclic codes over $S = F_{q} \times (F_{q} + v F_{q})$ , w…
