Title: Stanley-Reisner ideals from poset partitions.
Abstract: We show how one to classes of order preserving
maps P -> N, where P is a finite poset, and N the natural numbers
may associate wide classes of Stanley-Reisner ideals. These ideals
have very good and interesting properties with respect to:
1. Free resolutions
2. Associated simplicial complexes which are balls and spheres.
3. Their deformation theory to varieties.
