A site which outlines the history and details of Superstring theory, as seen by one of its pioneers, Dr John Schwarz

In this review I discuss some basic aspects of non-perturbative string theory. The topics include test of duality symmetries based on the analysis of the low energy effective action and the spectrum of BPS states, relationship between different duality symmetries, an introduction to M- and F-theories, black hole entropy in string theory, and Matrix theory.

The theory formerly known as strings is presented in a non-technical format.

Site discusses string theory, m-theory, gravity, and modification to m-theory.

Introduction to superstrings, M-theory, D-branes, p-branes, membranes, string theory, supergravity, supersymmetry

These lecture notes review the foundations and some applications of light-cone quantization.[Postscript]

Recent progress on string theory in curved spacetimes is reviewed. The string dynamics in cosmological and black hole spacetimes is investigated and the methods of solving the string equations of motion in curved spacetimes are described.

These four lectures, addressed to an audience of graduate students in experimental high energy physics, survey some of the basic concepts in string theory. The purpose is to convey a general sense of what string theory is and what it has achieved.[Postscript]

Pages for the String Theory-Conference of 2003 held in Kyoto, Japan.

In these lecture notes, an introduction to superstring theory is presented. Classical strings, covariant and light-cone quantization, supersymmetric strings, anomaly cancelation, compactification, T-duality, supersymmetry breaking, and threshold corrections to low-energy couplings are discussed. A brief introduction to non-perturbative duality symmetries is also included.

The purpose of this manuscript is to provide a pedagogical account of the brane technology so that the relativists can use branes in their study.
