Killing-Yano Supersymmetry in String Theory
F. De Jonghe, K. Peeters, K. Sfetsos
The presence of Killing-Yano tensors implies the existence of non-standard supersymmetries in point particle theories on curved backgrounds. In a string theoretical context these a…
The BPHZ renormalised BV master equation and Two-loop Anomalies in Chiral Gravities
Frank De Jonghe, Jordi Paris, Walter Troost
Anomalies and BRST invariance are governed, in the context of Lagrangian Batalin-Vilkovisky quantization, by the master equation, whose classical limit is . Using Zimmerm…
Redefining B-twisted topological sigma models
F. De Jonghe, P. Termonia, W. Troost +1
A recently proposed variation on the usual procedure to perform the topological B-twist in rigid models is applied to the case of the model on a Kähler manifold. This lea…
BRST Gauge Fixing and Regularization
P. H. Damgaard, F. De Jonghe, R. Sollacher
In the presence of consistent regulators, the standard procedure of BRST gauge fixing (or moving from one gauge to another) can require non-trivial modifications. These modificatio…
An alternative BRST operator for topological Landau-Ginzburg models
F. De Jonghe, P. Termonia, W. Troost +1
We propose a new BRST operator for the B-twist of Landau-Ginzburg (LG) models. It solves the problem of the fractional ghost numbers of Vafa's old BRST operator and shows how…
The Batalin-Vilkovisky Lagrangian quantisation scheme, with applications to the study of anomalies in gauge theories
Frank De Jonghe
Only the first 15 percent of the file survived the censor that is hidden in the network resources in a previous attempt to submit this thesis to the bulletin board. Hopefully this…
