New solutions to an old equation
Frederik Denef, Joris Raeymaekers, Walter Troost
We present a brief historical overview of the classical theory of a radiating point charge, described by the Lorentz-Dirac equation. A recent development is the discovery of tunnel…
A detailed case study of the rigid limit in Special Kähler geometry using K3
Marco Billo, Frederik Denef, Pietro Fre +4
This is a résumé of an extensive investigation of some examples in which one obtains the rigid limit of N=2 supergravity by means of an expansion around singular points in the modu…
The Definitions of Special Geometry
Ben Craps, Frederik Roose, Walter Troost +1
The scalars in vector multiplets of N=2 supersymmetric theories in 4 dimensions exhibit `special Kaehler geometry', related to duality symmetries, due to their coupling to the vect…
Classical Tunneling from the Lorentz-Dirac Equation
Frederik Denef, Joris Raeymaekers, Urban M. Studer +1
The classical equation of motion of a charged point particle, including its radiation reaction, is described by the Lorentz-Dirac equation. We found a new class of solutions that d…
BRST-Antibracket Cohomology in 2D Conformal Gravity
Friedemann Brandt, Walter Troost, Antoine Van Proeyen
We present results of a computation of the BRST-antibracket cohomology in the space of local functionals of the fields and antifields for a class of 2d gravitational theories which…
Regularization and the BV Formalism
Walter Troost, Antoine Van Proeyen
We summarize the application of the field--antifield formalism to the quantization of gauge field theories. After the gauge fixing, the main issues are the regularization and anoma…
