W-algebras from symplectomorphisms
G. Bandelloni, S. Lazzarini
It is shown how -algebras emerge from very peculiar canonical transformations with respect to the canonical symplectic structure on a compact Riemann surface. The action of smoo…
Short distance behaviour of correlators in the 2D Ising model in a magnetic field
M. Caselle, P. Grinza, N. Magnoli
We study the spin-spin, spin-energy and energy-energy correlators in the 2d Ising model perturbed by a magnetic field. We compare the results of a set of high precision Montecarlo…
Further comments on the background field method and gauge invariant effective actions
Carlo Becchi, Renzo Collina
The aim of this paper is to give a firm and clear proof of the existence in the background field framework of a gauge invariant effective action for any gauge theory ({\it backgrou…
On the Beta Function in Supersymmetric Gauge Theories
G. Carlino, K. Konishi, N. Maggiore +1
We re-examine perturbative and nonperturbative aspects of the beta function in N=1 and N=2 supersymmetric gauge theories, make comments on the recent literature on the subject and…
