A class of Ramsey-extremal hypergraphs
(University of Isfahan, 2017-09-01)In 1991, McKay and Radziszowski proved that, however each $3$-subset of a $13$-set is assigned one of two colours, there is some $4$-subset whose four $3$-subsets have the same colour. More than 25 years later, ...

Distance in cayley graphs on permutation groups generated by $k$ $m$-Cycles
(University of Isfahan, 2017-09-01)In this paper, we extend upon the results of B. Suceav{u{a}} and R. Stong [Amer. Math. Monthly, 110 (2003) 162--162], which they computed the minimum number of 3-cycles needed to generate an even permutation.

Binary sequence/array pairs via diference set pairs: A recursive approach
(University of Isfahan, 2017-09-01)Binary array pairs with optimal/ideal correlation values and their algebraic counterparts textquotedblleft difference set pairstextquotedblright;(DSPs) in abelian groups are studied. In addition to generalizing known ...

On the hilbert series of binomial edge ideals of generalized trees
(University of Isfahan, 2017-09-01)In this paper we introduce the concept of generalized trees and compute the Hilbert series of their binomial edge ideals.
