SOLITONS, BLACK-HOLES AND DUALITY IN STRING THEORY

These lectures are intended as an introduction to some of the basic as pects of string solitons, duality and black holes. We begin with a dis cussion of the role of classical solutions in duality, then focus on s tring/string duality and fundamental membranes. Finally, we examine th e feature of compositeness of string solitons, and its implications fo r bound states and black hole thermodynamics. As these lectures are ai med primarily at those less familiar with this field, technical detail s are minimized.
