To control supersymmetry and gauge invariance in super-Yangâ€“Mills theories we introduce new fields, called shadow fields, which enable us to enlarge the conventional Faddeevâ€“Popov framework and writeâ€¦ (More)

With the introduction of shadow fields, we demonstrate the renormalizability of the N = 4 super-Yangâ€“Mills theory in component formalism, independently of the choice of UV regularization. Remarkably,â€¦ (More)

A field theoretical framework for the recently proposed photon condensation effect in a nonlinear Fabry-Perot cavity is discussed. The dynamics of the photon gas turns out to be described by anâ€¦ (More)

Perturbation theory for a class of topological field theories containing antisymmetric tensor fields is considered. These models are characterized by a supersymmetric structure which allows toâ€¦ (More)

An algebraic proof of the nonrenormalization theorem for the perturbative beta function of the coupling constant of N = 2 Super Yangâ€“Mills theory is provided. The proof relies on a fundamentalâ€¦ (More)

The Wess-Zumino consistency conditions for Lorentz and diffeomorphism anomalies are discussed by introducing an operator Î´ which allows to decompose the exterior space-time derivative as a BRSâ€¦ (More)

The local composite operator A Î¼ is added to the Zwanziger action, which implements the restriction to the Gribov region Î© in Euclidean Yang-Mills theories in the Landau gauge. We prove thatâ€¦ (More)

The BRS transformations for gravity with torsion are discussed by using the Maurer-Cartan horizontality conditions. With the help of an operator Î´ which allows to decompose the exterior space-timeâ€¦ (More)

The nonabelian generalization of a recently proposed abelian axial gauge model for tensor matter fields is obtained. In both cases the model can be derived from a Ï†âˆ’type theory for antisymmetricâ€¦ (More)

A cohomological BRST characterization of the Seiberg-Witten (SW) map is given. We prove that the coefficients of the SW map can be identified with elements of the cohomology of the BRST operatorâ€¦ (More)
