This work is intended as a pedagogical introduction to M-theory and to its maximally
supersymmetric toroidal compactifications, in the frameworks of 11D supergravity, type II …

This article reviews the matrix model of M theory. M theory is an 11-dimensional quantum
theory of gravity that is believed to underlie all superstring theories. M theory is currently the …

Following is a collection of lecture notes on D–branes, which may be used by the reader as
preparation for applications to modern research applications such as: the AdS/CFT and …

We show that all supersymmetric Type IIA D-branes can be constructed as bound states of a
certain number of unstable non-supersymmetric Type IIA D9-branes. This string-theoretical …

In this review I discuss some basic aspects of non-perturbative string theory. The topics
include tests of duality symmetries based on the analysis of the low energy effective action …

We review our proposal for a constructive definition of superstring, type IIB matrix model. The
IIB matrix model is a manifestly covariant model for space-time and matter which possesses …

This is an expanded version of talks given by the author at the Trieste Spring School on
Supergravity and Superstrings in April of 1997 and at the accompanying workshop. The …

A bstract We consider (2+ 1)-dimensional (N, M)-extended higher-spin anti-de Sitter
supergravity and study its asymptotic symmetries. The theory is described by the Chern …

We study heterotic/type I duality in d= 8, 9 uncompactified dimensions. We consider the
special (” BPS-saturated”) F4 and R4 terms in the effective one-loop heterotic action, which …
