Abstract Six-dimensional (6D) superconformal field theories (SCFTs) occupy a central place
in the study of quantum field theories encountered in high energy theory. This article reviews …

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 …

We show that the large-N limits of certainconformal field theories in various dimensions
includein their Hilbert space a sector describing supergravityon the product of anti-de Sitter …

N= 2 supersymmetric gauge theories in four dimensions are studied by formulating them as
the quantum field theories derived from configurations of fourbranes, fivebranes, and …

T-Duality on a timelike circle does not interchange IIA and IIB string theories, but takes the
IIA theory to a type IIB∗ theory and the IIB theory to a type IIA∗ theory. The type II∗ theories …

We show that only by performing generalized dimensional reductions all possible brane
configurations are taken into account and one gets the complete lower-dimensional theory …

We review various aspects of classical solutions in string theories. Emphasis is placed on
their supersymmetry properties, their special roles in string dualities and microscopic …

Abstract Two-time physics (2T) is a general reformulation of one-time physics (1T) that
displays previously unnoticed hidden symmetries in 1T dynamical systems and establishes …

We study how to generate new Lie algebras G (N 0,…, N p,…, N n) from a given one G. The
(order by order) method consists in expanding its Maurer–Cartan one-forms in powers of a …
