We survey on-shell and off-shell higher derivative supergravities in dimensions 1≤ D≤ 11.
Various approaches to their construction, including the Noether procedure,(harmonic) …

We suggest and motivate a precise equivalence between uncompactified I I-dimensional M
theory and the N=∝ limit of the supersymmetric matrix quantum mechanics describing D0 …

We propose that the ten-dimensional E 8× E 8 heterotic string is related to an eleven-
dimensional theory on the orbifold R10× S1/Z2 in the same way that the Type IIA string in ten …

String theory is one of the most exciting and challenging areas of modern theoretical
physics. This book guides the reader from the basics of string theory to recent developments …

In this paper, we present a systematic analysis of eleven-dimensional supergravity on a
manifold with boundary, which is believed to be relevant to the strong coupling limit of the …

Recently it has been observed that branes in geometric engineering and holography have a
striking connection with generalized global symmetries. In this paper we argue that branes …

We study the properties of M and F theory compactifications to three and four dimensions
with background fluxes. We provide a simple construction of supersymmetric vacua …

In a certain strong coupling limit, compactification of the E8× E8 heterotic string on a Calabi-
Yau manifold X can be described by an eleven-dimensional theory compactified on X× S 1/Z …

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 …

Non-perturbative instanton corrections to the moduli space geometry of type IIA string theory
compactified on a Calabi-Yau space are derived and found to contain order e− 1/gs …
