Low Dimensional Sigma Models

Sigma models provide simple structures used in model building in elementary particle physics, and as such are a permanent tool which can be used by anyone who wants to employ field theoretical methods to the study of problems. Sigma models have attracted much recent interest, particularly because of their relevance in strings and superstrings. This introduction to the simple field theoretical structures used in theoretical models places particular emphasis on their application to elementary particle physics. The text examines the established ideas and applications of sigma models and presents them with more modern applications. Although written for both mathematicians and physicists, the text is primarily aimed at graduate students in theoretical particle physics.
