Generalized Born--Infeld Actions and Projective Cubic Curves
S. Ferrara, M. Porrati, A. Sagnotti +2
We investigate supersymmetric Born-Infeld Lagrangians with a second non-linearly realized supersymmetry. The resulting non-linear structure is more complex than the sq…
Renormalization of Massless Feynman Amplitudes in Configuration Space
Nikolay M. Nikolov, Raymond Stora, Ivan Todorov
A systematic study of recursive renormalization of Feynman amplitudes is carried out both in Euclidean and in Minkowski configuration space. For a massless quantum field theory (QF…
Two-Center Black Holes Duality-Invariants for stu Model and its lower-rank Descendants
Sergio Ferrara, Alessio Marrani, Emanuele Orazi +2
We classify 2-center extremal black hole charge configurations through duality-invariant homogeneous polynomials, which are the generalization of the unique invariant quartic polyn…
Renormalized Perturbation Theory: A Missing Chapter
Raymond Stora
Renormalized perturbation theory à la BPHZ can be founded on causality as analyzed by H. Epstein and V. Glaser in the seventies. Here, we list and discuss a number of additional co…
A Class of Topological Actions
M. Bauer, G. Girardi, R. Stora +1
We review definitions of generalized parallel transports in terms of Cheeger-Simons differential characters. Integration formulae are given in terms of Deligne-Beilinson cohomology…
Exercises in equivariant cohomology and topological theories
Raymond Stora
Equivariant cohomology is suggested as an alternative algebraic framework for the definition of topological field theories constructed by E. Witten circa 1988. It also enlightens t…
