Instabilities of internal gravity waves in the two-dimensional Boussinesq system
R. Bianchini, A. Maspero, S. Pasquali
We consider a two-dimensional, incompressible, inviscid fluid with variable density, subject to the action of gravity. Assuming a stable equilibrium density profile, we adopt the s…

Sharp asymptotic stability of the incompressible porous media equation
Roberta Bianchini, Min Jun Jo, Jaemin Park +1
In this paper, we prove the asymptotic stability of the incompressible porous media (IPM) equation near a stable stratified density, for initial perturbations in the Sobolev space…

Non Existence and Strong Ill-Posedness in for the Stable IPM Equation
Roberta Bianchini, Diego Córdoba, Luis MartÃnez-Zoroa
We prove the non-existence and strong ill-posedness of the Incompressible Porous Media (IPM) equation for initial data that are small perturbations of the linea…
