The condition for a sequence to be potentially $A_{L, M}$- graphic
(University of Isfahan, 2017-03-01)The set of all non-increasing non-negative integer sequences $pi=(d_1, d_2,ldots,d_n)$ is denoted by $NS_n$. A sequence $piin NS_{n}$ is said to be graphic if it is the degree sequence of a simple graph $G$ on $n$ ...

On the skew spectral moments of graphs
(University of Isfahan, 2017-03-01)Let $G$ be a simple graph, and $G^{sigma}$ be an oriented graph of $G$ with the orientation $sigma$ and skew-adjacency matrix $S(G^{sigma})$. The $k-$th skew spectral moment of $G^{sigma}$, denoted by ...

A family of $t$-regular self-complementary $k$-hypergraphs
(University of Isfahan, 2017-03-01)We use the recursive method of construction large sets of t-designs given by Qiu-rong Wu (A note on extending t-designs, {em Australas. J. Combin.}, {bf 4} (1991) 229--235.), and present a similar method for ...
