Abstract

Inspired by the definition of t\bf{t}-spread monomial ideals, in this paper, we introduce t\bf{t}-spread dd-partite hypergraph KVtK^{\bf t}_V and study its edge ideal I(KVt)I(K^{\bf t}_V). We prove that I(KVt)I(K^{\bf t}_V) has linear quotients, all powers of I(KVt)I(K^{\bf t}_V) have linear resolution and the Rees algebra of I(KVt)I(K^{\bf t}_V) is a normal Cohen-Macaulay domain. It is also shown that I(KVt)I(K^{\bf t}_V) is normally torsion-free and a complete characterization of Cohen-Macaulay S/I(KVt)S/I(K^{\bf t}_V) is given.
