E-raamat: Compact Matrix Quantum Groups and Their Combinatorics

This book is an introduction to the theory of compact quantum groups, an active research topic, emphasizing the combinatorial aspects. It also describes interactions with other fields of mathematics like quantum information theory, graph theory and non-commutative probability. Intended for graduate students, undergraduate students and researchers.

An organised step-by-step introduction to the theory of compact quantum groups, starting with examples coming from quantum physics, which stems from the basic undergraduate mathematics curriculum. Introducing more abstract concepts along the way when needed, the reader is led from the fundamentals of the theory to recent research results. The emphasis is put on the combinatorics underlying compact quantum groups, which is very elementary to describe but leads to profound results. This book includes many exercises to help students work through new concepts and ideas and consolidate their understanding. The theory itself is illustrated by an array of examples, some related to other fields of Mathematics such as free probability theory or graph theory. The book is intended for graduate students, motivated undergraduate students and researchers.
