Jacobi Forms, Finite Quadratic Modules and Weil Representations over Number Fields

Introduction

"Jacobi Forms, Finite Quadratic Modules and Weil Representations over Number Fields" is an in-depth exploration of advanced topics in modern number theory, algebra, and modular forms. This book delves into the profound interactions between three seemingly disparate mathematical structures: Jacobi forms, finite quadratic modules, and Weil representations, particularly in the context of number fields. It offers both graduate students and researchers a clear and comprehensive treatment of these subjects, making complex topics accessible while maintaining mathematical rigor.

The journey begins with the foundations, introducing readers to the underlying mathematical machinery upon which the entire theory is built. From modular forms and their generalization to Jacobi forms, to the significant role played by finite quadratic modules and their connection to Weil representations, the book ties together topics that frequently appear across arithmetic geometry, algebraic representation theory, and automorphic forms.

This work is structured to build bridges between theoretical concepts and practical applications. Whether you are approaching the subject as a novice or an experienced mathematician, the book provides clarity in its exposition of complicated ideas, fostering deeper insight into these sophisticated mathematical tools.

Detailed Summary of the Book

At its core, this book explores the intricate interplay between Jacobi forms and various algebraic frameworks, emphasizing their applications over number fields.

The opening chapters establish the groundwork, starting with an introduction to modular and Jacobi forms. These objects, pivotal in many areas of mathematics and physics, are introduced with a thorough analysis of their fundamental definitions, properties, and examples. The discussion then expands to generalizations of these forms over number fields rather than the classical rational field, allowing for a broader perspective that illuminates previously inaccessible structures.

Next, the book delves into finite quadratic modules, exploring their algebraic properties and the crucial role they play in understanding modular forms. Their interactions with Weil representations, another critical theme in the text, are explored in great detail, providing precise and elegant connections between these algebraic structures and automorphic forms.

Subsequent chapters focus on the theory of Weil representations over various number fields and their interplay with modular and Jacobi forms. The book progressively builds a framework unifying these topics, offering readers a coherent understanding of their interdependencies.

By combining theory with illustrative examples and exercises, the text gradually exposes readers to the power and utility of these structures in both pure and applied mathematics. It also opens doors to questions in arithmetic geometry and mathematical physics, where these objects find natural applications, thus bridging mathematical theory with real-world phenomena.
