Large Deviation Approach to the Randomly Forced Navier-Stokes Equation
R. Collina, R. Livi, A. Mazzino
The random forced Navier-Stokes equation can be obtained as a variational problem of a proper action. By virtue of incompressibility, the integration over transverse components of…
Self-similar behavior of pre-turbulent fluctuations
R. Collina, R. Livi, A. Mazzino
The random forced Navier-Stokes equation can be obtained as a variational problem of a proper action. In virtue of incompressibility, the integration over transverse components of…
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…
