Abstract

Let $S=\mathbb K[x_1,\ldots,x_n]$ the polynomial ring over a field $\mathbb K$. In this paper for some families of monomial ideals $I \subset S$ we study the minimal number of generators of $I^k$. We use this results to find some other Betti numbers of these families of ideals for special choices of $n$, the number of variables.
