A co-publication of the AMS and Centre de Recherches Mathématiques

Papers in this volume are based on the Workshop on Symmetries in
Physics held at the Centre de recherches mathématiques (University of
Montreal) in memory of Robert T. Sharp. Contributed articles are on a variety
of topics revolving around the theme of symmetry in physics.

The preface presents a biographical and scientific retrospect of the life
and work of Robert Sharp. Other articles in the volume represent his diverse
range of interests, including representation theoretic methods for Lie
algebras, quantization techniques and foundational considerations, modular
group invariants and applications to conformal models, various physical models
and equations, geometric calculations with symmetries, and pedagogical methods
for developing spatio-temporal intuition.

The book is suitable for graduate students and researchers interested in
group theoretic methods, symmetries, and mathematical physics.

Titles in this series are co-published with the Centre de Recherches Mathématiques.

#### Readership

Graduate students and research mathematicians interested in applications of group theory in physics.
