Abstract
We prove a formula, conjectured by Conca and Herzog, for the number of all families of nonintersecting lattice paths with certain starting and end poi nts in a region that is bounded by an upper ladder. Thus we are able to com pute explicitly the Hilbert series for certain one-sided ladder determinant al rings.
