The present volume is the proceedings of the conference “Algebraic Analysis and Around”, in honor of Professor Masaki Kashiwara's 60th birthday, held in Kyoto in June, 2007. Most of the papers contributed in this volume are based on the talks given in the conference, and the subjects discussed here contain D-modules, micro-local analysis, representation theory, integrable systems, to which Kashiwara's contribution and influence are really profound. The readers may find groundbreaking materials for the future in mathematics.Published by Mathematical Society of Japan and distributed by World Scientific Publishing Co. for all markets except North America
