PREFACE
The underlying goal ofthis string conference was to identify future trends
in string theory. We therefore had several talks in string theory itself, string
phenomenology, exact solutions and mirror symmetry. There was also an
informal discussion on the future of string theory.
The timing of Strings '95 at USC was very fortuitous as some extremely
beautiful and far reaching work was done in 1994. Among the most influential
research was that of Seiberg and Witten, Schwarz and Sen and Hull and
Townsend. This laid the foundation for much future work on exact non
perturbative quantum effective actions, duality symmetries and the string
theoretic generalizations of these ideas. All these subjects came together at
Strings '95, resulting in a very exciting and stimulating conference. It was the
first time that many of the new developments has been discussed at a conference.
