#### A Global well-posedness result for the Rosensweig system of ferrofluids

(2019)

In this Paper we study a Bloch-Torrey regularization of the Rosensweig system for ferrofluids. The scope of this paper is twofold. First of all, we investigate the existence and uniqueness of Leray-Hopf solutions of this ...

#### Models for damped water waves

(2019)

In this paper we derive some new weakly nonlinear asymptotic models describing
viscous waves in deep water with or without surface tension effects. These asymptotic models
take into account several different dissipative ...

#### On the influence of gravity on density-dependent incompressible periodic fluids

(2019)

The present work is devoted to the analysis of density-dependent, incompressible fluids in a 3D torus, when the Froude number $\varepsilon$ goes to zero. We consider the very general case where the initial data do not have ...

#### Asymptotic models for free boundary flow in porous media

(2019)

We provide rigorous asymptotic models for the free boundary Darcy and Forchheimer problem under the assumption of weak nonlinear interaction, in a regime in which the steepness parameter of the interface is considered to ...

#### Some remark on the existence of infinitely many nonphysical solutions to the incompressible Navier-Stokes equations

(2018-10)

We prove that there exist infinitely many distributional solutions with infinite kinetic energy to both the incompressible Navier-Stokes equations in $ \mathbb{R}^2 $ and Burgers equation in $\mathbb{R} $ with vanishing ...

#### On the global well-posedness of a class of 2D solutions for the Rosensweig system of ferrofluids

(2018-09)

We study a class of 2D solutions of a Bloch-Torrey regularization of the Rosensweig system in the whole space, which arise when the initial data and the external magnetic field are 2D. We prove that such solutions are ...

#### Zero limit of entropic relaxation time for the Shliomis model of ferrofluids

(2018-02-11)

We construct solutions for the Shilomis model of ferrofluids in a critical space, uniformly in the entropic relaxation time $ \tau \in (0, \tau_0) $. This allows us to study the convergence when $ \tau\to 0 $ for such solutions.

#### Dispersive effects of weakly compressible and fast rotating inviscid fluids

(2017-08)

We consider a system describing the motion of an isentropic, inviscid, weakly compressible, fast rotating fluid in the whole space $\mathbb{R}^3$, with initial data belonging to $ H^s \left( \mathbb{R}^3 \right), s>5/2 $. ...

#### Derivation of limit equation for a singular perturbation of a 3D periodic Boussinesq system

(2017-07-15)

We consider a system describing the dynamics of an hydrodynamical, density-dependent flow under the effects of gravitational forces. We prove that if the Froude number is sufficiently small such system is globally well ...

#### Highly rotating fluids with vertical stratification for periodic data and vanishing vertical viscosity

(2017-07)

We prove that the three-dimensional, periodic primitive equations with zero vertical diffusivity are globally well posed if the Rossby and Froude number are sufficiently small. The initial data is considered to be of zero ...
