摘要：
Given a finite simplicial complex L and a collection of pairs of spaces indexed by the vertices of L, one can define the “polyhedral product” of the collection with respect to L. We record a simple formula for its Euler characteristic. In special cases the formula simplifies further to one involving the h-polynomial of L.
