Objective

Commutative algebra has been developed in step with algebraic geometry and has played an essential role in its foundation. In 1975, however, a new trend of commutative algebra arose with the work of Richard Stanley who used the theory of Cohen-Macaulay rings to prove affirmatively the Upper Bound Conjecture for spheres. It then turned out that commutative algebra supplies basic methods in the algebraic study of combinatorics on convex polytopes and simplicial complexes. In the last decade, combinatorial commutative algebra has been one of the most active topics in Mathematics. Almost six years ago, the study of combinatorial commutative algebra was started in Iran and now we are glad to witness that there are several colleagues and students working in this area.

It is our pleasure to inform you about the second seminar in combinatorial commutative algebra which will be held on February 8 and 9, 2012 (Bahman 19 and 20, 1390), at the School of Mathematics of IPM, Tehran, Iran.

The goal of this session is to bring together many of the people in Iran who are working in combinatorial commutative algebra, to introduce students and young researchers the topics of recent research and to set up new directions for future investigations.
