Representation Theory and Complex Analysis: Lectures given at the C.I.M.E. Summer School held in Venice, Italy June 10–17, 2004

Detailed Summary of the Book

The book comprises lectures that explore the crossroads of representation theory and complex analysis, making it an excellent introduction for newcomers while offering fresh insights to seasoned experts. Starting with an exposition of representation theory, the contributors highlight its role in elucidating the structure of groups and algebras. Readers are introduced to the foundational principles of unitary representations and their applications in analyzing symmetries.

Following this, the focus shifts to the powerful techniques of complex analysis, particularly its use in describing geometrical objects and solving functional equations. Special attention is given to Lie groups and their representations, with discussions on key tools like Harish-Chandra’s theory, Plancherel theorems, and characters of representations.

The later chapters delve into applications, such as the relationships between automorphic forms, geometry, and number theory. These sections illuminate how representation theory acts as a bridge, uniting diverse mathematical realms. The integration of differential operators and geometric methods further emphasizes the synergy between representation theory and complex analysis.
