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 ERG approach in Well Developed Turbulence
Renzo Collina, Paolo Tomassini
We apply the method of the Renormalization Group (GR), following the Polchinski point of view, to a model of well developed and isotropic fluid turbulence. The Galilei-invariance i…
A Functional and Lagrangian Formulation of Two-Dimensional Topological Gravity
C. M. Becchi, R. Collina, C. Imbimbo
We reconsider two-dimensional topological gravity in a functional and lagrangian framework. We derive its Slavnov-Taylor identities and discuss its (in)dependence on the background…
On the Semi-Relative Condition for Closed (TOPOLOGICAL) Strings
C. M. Becchi, R. Collina, C. Imbimbo
We provide a simple lagrangian interpretation of the meaning of the semi-relative condition in closed string theory. Namely, we show how the semi-relative condition is equi…
