Continuity equations and ODE flows with non-smooth velocity [PDF]
In this paper we review many aspects of the well-posedness theory for the Cauchy problem for the continuity and transport equations and for the ordinary differential equation (ODE). In this framework, we deal with velocity fields that are not smooth, but

Poisson Structures for PDEs Associated with Diffeomorphism Groups [PDF]
We study Poisson and Lie-Poisson structures on the diffeomorphism groups with a smooth metric spray in connection with dynamics of nonlinear PDEs. In particular, we provide a precise analytic sense in which the time t map for the Euler equations of an ...

New approaches to nonlinear waves
The book details a few of the novel methods developed in the last few years for studying various aspects of nonlinear wave systems. The introductory chapter provides a general overview, thematically linking the objects described in the book. Two chapters

Efficient upwind algorithms for solution of the Euler and Navier-stokes equations [PDF]
An efficient three-dimensionasl tructured solver for the Euler and Navier-Stokese quations is developed based on a finite volume upwind algorithm using Roe fluxes. Multigrid and optimal smoothing multi-stage time stepping accelerate convergence.

On the use of tent spaces for solving PDEs: A proof of the Koch-Tataru theorem
Lecture notes with complete detailsInternational audienceIn these notes we will present (a part of) the parabolic tent spaces theory and then apply it in solving some PDE's originated from the fluid mechanics.
