The first International Conference on Commutative Algebra in Yokohama was organized by Shiro Goto and Kei-ichi Watanabe and held in August of 2001. This is the second time, which is performed as one of the activities of Meiji Institute for Advanced Study of Mathematical Sciences (MIMS). The fund for the conference comes from Research Project Grant (A) of Institute of science and Technology of Meiji University. The students of Meiji University among the participants are partially supported by Support Program for Improving Graduate School Education (GP).
