Modular invariant partition functions for non-compact G/Ad(H) models
Jonas Bjornsson, Jens Fjelstad
We propose a spectrum for a class of gauged non-compact G/Ad(H) WZNW models, including spectrally flowed images of highest, lowest, and mixed extremal weight modules. These are com…
Multi-loop amplitudes in maximally supersymmetric pure spinor field theory
Jonas Bjornsson
This paper provides a more detailed background to the results of arXiv:1004.2692 concerning properties of multi-loop amplitudes in a pure spinor formulation of field theories with…
On the unitarity of gauged non-compact world-sheet supersymmetric WZNW models
Jonas Bjornsson, Stephen Hwang
In this paper we generalize our investigation of the unitarity of non-compact WZNW models connected to Hermitian symmetric spaces to the N=1 world-sheet supersymmetric extension of…
On small tension p-branes
Jonas Bjornsson, Stephen Hwang
This paper deals with p-branes with small but non-zero tension. We prove the existence of canonical transformations, within a perturbation theory, that link specific geometries of…
On the unitarity of gauged non-compact WZNW strings
Jonas Bjornsson, Stephen Hwang
In this paper we investigate the unitarity of gauged non-compact WZNW strings i.e. string theories formulated as G/H' WZNW models, where G is a non-compact group. These models repr…
The BRST treatment of stretched membranes
Jonas Bjornsson, Stephen Hwang
The BRST-invariant formulation of the bosonic stretched membrane is considered. In this formulation the stretched membrane is given as a perturbation around zero-tension membranes,…
