**Introduction to Representations of Real Semisimple Lie Groups**

by **Matvei Libine** - **arXiv** , **2012**

These are lecture notes for a one semester introductory course I gave at Indiana University. The goal was to make this exposition as clear and elementary as possible. A particular emphasis is given on examples involving SU(1,1).

**Symplectic Reflection Algebras**

by **Gwyn Bellamy** - **arXiv** , **2012**

The emphasis throughout is on examples to illustrate the many different facets of symplectic reflection algebras. Exercises are included at the end of each lecture in order for the student to get a better feel for these algebras.

**Lectures on Representations of Complex Semi-Simple Lie Groups**

by **Thomas J. Enright** - **Tata Institute of Fundamental Research** , **1981**

The purpose of these lectures is to describe a factorial correspondence between the theory of admissible representations for a complex semisimple Lie group and the theory of highest weight modules for a semisimple Lie algebra.

**Lectures on Some Aspects of p-Adic Analysis**

by **F. Bruhat** - **Tata Institute of Fundamental Research** , **1963**

The text covers the classical theory of valuated fields, results about representations of classical groups over a locally compact valuated field, and Dwork's proof of the rationality of the zeta function of an algebraic variety over a finite field.

**Lectures on Lie Groups and Representations of Locally Compact Groups**

by **F. Bruhat** - **Tata Institute of Fundamental Research** , **1958**

We consider some heterogeneous topics relating to Lie groups and the general theory of representations of locally compact groups. We have rigidly adhered to the analytic approach in establishing the relations between Lie groups and Lie algebras.

**Finite Group Representations for the Pure Mathematician**

by **Peter Webb** - **University of Minnesota** , **2007**

The book is intended to be used as a learning tool by people who do not know the subject. It is intended to be appropriate for non-specialists in the area of representation theory, such as those whose primary interest is topology or combinatorics.

**Lectures on Representation Theory and Invariant Theory**

by **William Crawley-Boevey** - **University of Leeds** , **1990**

These are lectures on the symmetric group, the general linear group and invariant theory. The course covered as much of the classical theory as time allowed. The text requires some knowledge of rings and modules, character theory, affine varieties.

**Groups: Presentations and Representations**

by **Christopher Cooper** - **Macquarie University** , **2008**

This is a first course on group theory suitable to a third year student. It motivates group theory with many illustrative examples such as shuffling of cards and permutation puzzles. There's an elementary introduction to representation theory.

**An Elementary Introduction to Groups and Representations**

by **Brian C. Hall** - **arXiv** , **2000**

An elementary introduction to Lie groups, Lie algebras, and their representations. Topics include definitions and examples of Lie groups and Lie algebras, the basics of representations theory, the Baker-Campbell-Hausdorff formula, and more.

**Introduction to Representation Theory**

by **Pavel Etingof, at al.** - **MIT** , **2009**

Representation theory studies symmetry in linear spaces. It is a beautiful mathematical subject which has many applications, ranging from number theory and combinatorics to geometry, probability theory, quantum mechanics and quantum field theory.

**Varieties of Lattices**

by **Peter Jipsen, Henry Rose** - **Springer** , **1992**

Presents the main results about modular and nonmodular varieties, equational bases and the amalgamation property in a uniform way. The text includes preliminaries that make the material accessible to anyone with basic knowledge of universal algebra.
