Prospects from Strings and Branes
Alexander Sevrin
A brief, non-technical and non-exhaustive review of D(irichlet)-branes and (some) of their applications is given.
Gauging Wess-Zumino-Witten Models
A. Sevrin
We review some aspects of gauged WZW models. By choosing a nilpotent subgroup as gauge group, one is lead to three main applications: the construction of field theories with an ext…
Quantum W_3 Gravity
Kareljan Schoutens, Alexander Sevrin, Peter van Nieuwenhuizen
We briefly review some results in the theory of quantum gravity in the chiral gauge. We compare them with similar results in the analogous but simpler cases of induced…
Superspace WZW Models and Black Holes
Changhyun Ahn, Martin Rocek, Kareljan Schoutens +1
We show how to write an off-shell action for the supersymmetric WZW model in terms of chiral and twisted chiral multiplets. We discuss the supersymme…
