We describe Stochastic Loewner Evolution on arbitrary Riemann surfaces with boundary using Conformal Field Theory methods. We propose in particular a CFT construction for a probability measure onâ€¦ (More)

We find novel bound states of NS5, D6 and D8-branes in massive type IIA string theory. As the NS gauge transformations can change the Chern class of the RR field these configurations should beâ€¦ (More)

In this paper we continue the study of the non-critical type 0 string and its field theory duals. We begin by reviewing some facts and conjectures about these theories. We move on to our proposal forâ€¦ (More)

We investigate consistency conditions for supersymmetric gauge theories in higher dimensions. First, we give a survey of Seibergâ€™s necessary conditions for the existence of such theories with simpleâ€¦ (More)

The Weyl anomaly in the Holographic Renormalisation Group as implemented using Hamiltonâ€“Jacobi language is studied in detail. We investigate the breakdown of the descent equations in order to isolateâ€¦ (More)

We consider four-graviton scattering in Type II string theory on one-loop level in the large centre of mass energy M limit. We extract from it an explicit integral expression for the full stringâ€¦ (More)

We cast M-brane interactions including intersecting membranes and five-branes in manifestly gauge invariant form using an arrangement of higher dimensional Dirac surfaces. We show that theâ€¦ (More)

We discuss the geometry of string and M-theory gauge fields in Deligne cohomology. In particular, we show how requiring string structure (or loop space Spin structure) on the five brane leads toâ€¦ (More)

We find the Holographic Renormalization Group equations for the holographic duals of generic gravity theories coupled to form fields and spin2 fermions. Using Hamiltonâ€“Jacobi theory we discuss theâ€¦ (More)

The infinitesimal symmetries of a fully decomposed non-Abelian gerbe can be generated in terms of a nilpotent BRST operator, which is here constructed. The appearing fields find a naturalâ€¦ (More)
