The map between conformal hypercomplex/hyper-Kahler and quaternionic(-Kahler) geometry (2006)
Cucu, S, De Wit, T, Gheerardyn, J, Vandoren, S
We review the general properties of target spaces of hypermultiplets, which are quaternionic-like manifolds, and discuss the relations between these manifolds and their symmetry generators. We...
N=2 supergravity in five dimensions revisited (2004)
Bergshoeff, E, Cucu, S, De Wit, T, Vandoren, S
We construct matter-coupled N = 2 supergravity in five dimensions, using the superconformal approach. For the matter sector we take an arbitrary number of vector, tensor and hypermultiplets. By...

Superconformal N=2, D=5 matter with and without actions (2002)
Bergshoeff, E, De Wit, T, Halbersma, R, ...
We investigate N = 2, D = 5 supersymmetry and matter-coupled supergravity theories in a superconformal context. In a first stage we do not require the existence of a lagrangian. Under this...
An alternative brst operator for topological landau-ginzburg models (1995)
We propose a new BRST operator for the B-twist of N = 2 Landau-Ginzburg (LG) models, It solves the problem of the fractional ghost numbers of Vafa's old BRST operator and shows how the model is...
The regularized BRST Jacobian of pure Yang-Mills theory (1992)
Vandoren, S, Vannieuwenhuizen, P
The jacobian for infinitesimal BRST transformations of path integrals for pure Yang-Mills theory, viewed as a matrix 1+DELTAJ in the space of Yang-Mills fields and (anti)ghosts, contains off-diagonal...
