A paradifferential approach for well-posedness of the Muskat problem

HQ Nguyen, B Pausader - Archive for Rational Mechanics and Analysis, 2020 - Springer
We study the Muskat problem for one fluid or two fluids, with or without viscosity jump, with or
without rigid boundaries, and in arbitrary space dimension d of the interface. The Muskat …

[BOOK][B] Global regularity for gravity unstable Muskat bubbles

In this paper, we study the dynamics of fluids in porous media governed by Darcy's law: the
Muskat problem. We consider the setting of two immiscible fluids of different densities and …

Global well-posedness for the three dimensional Muskat problem in the critical Sobolev space

F Gancedo, O Lazar - Archive for Rational Mechanics and Analysis, 2022 - Springer
We prove that the three dimensional stable Muskat problem is globally well-posed in the
critical Sobolev space H˙ 2∩ W˙ 1,∞ provided that the semi-norm‖ f 0‖ H˙ 2 is small …

[HTML][HTML] Surface tension stabilization of the Rayleigh-Taylor instability for a fluid layer in a porous medium

F Gancedo, R Granero-Belinchón… - Annales de l'Institut Henri …, 2020 - Elsevier
This paper studies the dynamics of an incompressible fluid driven by gravity and capillarity
forces in a porous medium. The main interest is the stabilization of the fluid in Rayleigh …

Global well‐posedness for the one‐phase Muskat problem

H Dong, F Gancedo, HQ Nguyen - Communications on Pure …, 2023 - Wiley Online Library
The free boundary problem for a two‐dimensional fluid permeating a porous medium is
studied. This is known as the one‐phase Muskat problem and is mathematically equivalent …

On Nonlinear Stability of Muskat Bubbles

F Gancedo, E García-Juárez, N Patel… - Journal de Mathématiques …, 2025 - Elsevier
In this paper we consider gravity-capillarity Muskat bubbles in 2D. We obtain a new
approach to improve our result in [1]. Due to a new bubble-adapted formulation, the …

Motility and morphodynamics of confined cells

I Lavi, N Meunier, R Voituriez, J Casademunt - Physical Review E, 2020 - APS
We introduce a minimal hydrodynamic model of polarization, migration, and deformation of a
biological cell confined between two parallel surfaces. In our model, the cell is driven out of …

The Hele-Shaw semi-flow

T Alazard, H Koch - arxiv preprint arxiv:2312.13678, 2023 - arxiv.org
We prove that the Cauchy problem is well-posed in a strong sense and in a general setting.
Our main result is the construction of an abstract semi-flow for the Hele-Shaw problem within …

The vanishing surface tension limit of the Muskat problem

PT Flynn, HQ Nguyen - Communications in Mathematical Physics, 2021 - Springer
The Muskat problem, in its general setting, concerns the interface evolution between two
incompressible fluids of different densities and viscosities in porous media. The interface …
