内容简介

　　This book offers a comprehensive survey of the area of monoids. It includes injective and weakly injective S-acts， the concept of projective S-acts， some fundamental and interesting results concerning strong flatness， condition（P） and flatness of S-acts， some results on homological classification of monoids， the study of sheaves for classes of monoids and S-acts， analogous to the sheaves for classes of rings and modules. This volume will be of interest to researchers， graduate students and scientists of mathematics.
