This book explores various properties of quasimodular forms, especially their connections with Jacobi-like forms and automorphic pseudodifferential operators. The material that is essential to the subject is presented in sufficient detail, including necessary background on pseudodifferential operators, Lie algebras, etc., to make it accessible also to non-specialists. The book also covers a sufficiently broad range of illustrations of how the main themes of the book have occurred in various parts of mathematics to make it attractive to a wider audience.
The book is intended for researchers and graduate students in number theory.

First book on quasimodular forms Presents all of the necessary basic materials on quasimodular forms and their relation to pseudodifferential operators, making the book accessible also to non-specialists Contains a nice selection of applications of the theory to a variety of other areas
