The GL(1|1) WZW model: From Supergeometry to Logarithmic CFT
Volker Schomerus, Hubert Saleur
We present a complete solution of the WZW model on the supergroup GL(1|1). Our analysis begins with a careful study of its minisuperspace limit (``harmonic analysis on the supergro…
Non-compact String Backgrounds and Non-rational CFT
Volker Schomerus
This is an introduction to the microscopic techniques of non-rational bulk and boundary conformal field theory which are needed to describe strings moving in non-compact curved bac…
Tensor products of psl(2|2) representations
Gerhard Gotz, Thomas Quella, Volker Schomerus
The aim of this work is to study finite dimensional representations of the Lie superalgebra psl(2|2) and their tensor products. In particular, we shall decompose all tensor product…
Representation theory of sl(2|1)
Gerhard Gotz, Thomas Quella, Volker Schomerus
In this note we present a complete analysis of finite dimensional representations of the Lie superalgebra sl(2|1). This includes, in particular, the decomposition of all tensor pro…
