## PHY7097: Introduction to String Theory

My aim in this one semester course is to provide a first introduction
to string theory for graduate students.
This is a very rich subject and there are many
approaches to it. In this course I will view string theory
as a new way to describe the same physics that quantum field
theory describes, as exemplified by the AdS/CFT correspondence.
We will not have much time to explore very deeply its other role as a vehicle
for the unification of gravity with the other forces of nature.

I expect to spend most of the semester
developing string theory in flat space-time, starting with
a thorough understanding of physical properties
of the tree level scattering amplitudes for the various types of strings.
This will lay a firm foundation for the consideration, toward
the end of the semester, of curved backgrounds,
such as Anti-deSitter space (AdS), which
provide the key to understanding quantum field theory in the
language of string.
Below are links to course information, a syllabus, a convention
and formula sheet.
