Absence of splash singularities for surface quasi-geostrophic sharp fronts and the Muskat problem
(National Academy of Sciences (United States), 2014)
In this paper, for both the sharp front surface quasi-geostrophic equation and the Muskat problem, we rule out the “splash singularity” blow-up scenario; in other words, we prove that the contours evolving from either of ...

Global regularity of 2D density patches for inhomogeneous Navier-Stokes
(Springer, 2018)
This paper is about Lions’ open problem on density patches: whether inhomogeneous incompressible Navier-Stokes equations preserve the initial regularity of the free boundary given by density patches. Using classical Sobolev ...

Contour dynamics of incompressible 3-D fluids in a porous medium with different densities
(Springer, 2007-07)
We consider the problem of the evolution of the interface given by two incompressible fluids through a porous medium, which is known as the Muskat problem and in two dimensions it is mathematically analogous to the two-phase ...

Lack of uniqueness for weak solutions of the incompressible porous media equation
(Springer, 2011-06)
In this work we consider weak solutions of the incompressible 2-D porous media equation. By using the approach of De Lellis-Sz´ekelyhidi we prove non-uniqueness for solutions in L∞ in space and time.

Finite time singularities for the free boundary incompressible Euler equations
(Princeton University, 2013)
In this paper, we prove the existence of smooth initial data for the 2D free boundary incompressible Euler equations (also known for some particular scenarios as the water wave problem), for which the smoothness of the ...

Free boundary and turbulence for incompressible viscous fluids
(2023-06-29)
The mathematical bases of the dynamics of viscous fluids are given by the classical Navier- Stokes equations, which model the motion of a viscous incompressible fluid. We can consider a wide variety of scenarios involving ...
