Raktažodžiai:
This book provides a thorough introduction to the theory of complex semisimple quantum groups, that is, Drinfeld doubles of q-deformations of compact semisimple Lie groups. The presentation is comprehensive, beginning with background information on Hopf algebras, and ending with the classification of admissible representations of the q-deformation of a complex semisimple Lie group.





 The main components are:





-   a thorough introduction to quantized universal enveloping algebras over general base fields and generic deformation parameters, including finite dimensional representation theory, the Poincaré-Birkhoff-Witt Theorem, the locally finite part, and the Harish-Chandra homomorphism,





-   the analytic theory of quantized complex semisimple Lie groups in terms of quantized algebras of functions and their duals,





-   algebraic representation theory in terms of category O, and





-   analytic representationtheory of quantized complex semisimple groups.





 Given its scope, the book will be a valuable resource for both graduate students and researchers in the area of quantum groups.

Recenzijos

The book is largely self-contained. It is highly recommended for mathematicians of all levels wishing to learn about these topics, in the algebraic setting and/or in the analytic setting. (Huafeng Zhang, zbMATH 1514.20006, 2023)
