In this series of 4 or 5 2-hour lectures, I'll describe some of the powerful exact results that one can achieve in supersymmetric theories. The topics will be as follows: Lecture 1: Non-Renormalization Theorems Lecture 2: Classical and Quantum Moduli Spaces Lecture 3: Superconformal Field Theories and Seiberg Duality Lecture 4: Central Charges, a-maximization, and the a-theorem Lecture 5 (if it happens): Brane Tilings and Dimers
