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…

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…
