Abstract: In this paper we study the behavior of the fractions of a factorial design under permutations of the factor levels. We code the s levels of a factor with the s-th roots of the unity.… read more here.

Abstract: Abstract In this paper, some algebraic and combinatorial characterizations of the spanning simplicial complex Δs(????n,m) of the Jahangir’s graph ????n,m are explored. We show that Δs(????n,m) is pure, present the formula for f-vectors associated to… read more here.
