A bstract We study the bosonic sector of a decoupling limit of type IIA superstring theory,
where a background Ramond-Ramond one-form is fined tuned to its critical value, such that …

In recent years there has been some progress in understanding how one might model the
interactions of branes in M-theory despite not having a fundamental perturbative description …

We study and extend the duality web unifying different decoupling limits of type II superstring
theories and M theory. We systematically build connections to different corners, such as …

We review different exact approaches to string theory. In the context of the Green–Schwarz
superstring, we discuss the action in curved backgrounds and its supercoset formulation …

We examine the T-duality relation between 1+ 1 NCOS and the DLCQ limit of type-IIA string
theory. We show that, as long as there is a compact dimension, one can meaningfully define …

Recently an action based on Lie 3-algebras was proposed to describe M2-branes. We study
the case of infinite dimensional Lie 3-algebras based on the Nambu-Poisson structure of …

We present two derivations of the multiple D2 action from the multiple M2-brane model
proposed by Bagger-Lambert and Gustavsson. The first one is to start from Lie 3-algebra …

By exploiting the BV quantization of topological bosonic open membrane, we argue that flat
3-form C-field leads to deformations of the algebras of multi-vectors on the Dirichlet-brane …

We show that field theories with light-like noncommutativity, that is with θ 0i=− θ 1i, are
unitary quantum theories, and that they can be obtained as decoupled field theory limits of …

We describe the quantization of 2-plectic manifolds as they arise in the context of the
quantum geometry of M-branes and non-geometric flux compactifications of closed string …
