Abstract : We nd some general lower bounds of the sum of certain families of multigraded
Betti numbers of any simplicial complex K with a vertex coloring.
These multigraded Betti numbers of K are intimately related to some quotient
spaces of the moment-angle complex of K under some free torus actions.
