We review the holographic correspondence between field theories and string/M theory,
focusing on the relation between compactifications of string/M theory on Anti-de Sitter …

We review the status of solitons in superstring theory, with a view to understanding the
strong coupling regime. These solitonic solutions are non-singular field configurations which …

The strong coupling dynamics of string theories in dimension d⩾ 4 are studied. It is argued,
among other things, that eleven-dimensional supergravity arises as a low energy limit of the …

This is an extended version of our short report [1], where a holographic interpretation of
entanglement entropy in conformal field theories is proposed from AdS/CFT …

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 …

We construct compact examples of D-manifolds for type IIB strings. The construction has a
natural interpretation in terms of compactification of a 12-dimensionalF-theory'. We provide …

The effective action for type II string theory compactified on a six-torus is N= 8 supergravity,
which is known to have an E7 duality symmetry. We show that this is broken by quantum …

We propose an explanation via string theory of the correspondence between the Coulomb
branch of certain three-dimensional supersymmetric gauge theories and certain moduli …

The recent discovery of an explicit conformal field theory description of Type II p-branes
makes it possible to investigate the existence of bound states of such objects. In particular, it …

It is shown that low-energy string theory admits a variety of solutions with the structure of an
extended object surrounded by an event horizon. In particular there is a family of black string …
