Combinatorics and Commutative Algebra Summary

Combinatorics and Commutative Algebra by Richard P. Stanley

* Stanley represents a broad perspective with respect to two significant topics from Combinatorial Commutative Algebra:

1) The theory of invariants of a torus acting linearly on a polynomial ring, and

2) The face ring of a simplicial complex

* In this new edition, the author further develops some interesting properties of face rings with application to combinatorics
