The Most Probable Outer Density Profile from Excursion Set Theory

Ericka Florio, Vasiliki Pavlidou

Measurements of the turnaround radius around galaxy clusters can be used to break the degeneracy between measurements of the present day energy density of matter and dark energy. K…

Generalized solution and Weak-Strong uniqueness for a barotropic Euler-Riesz system

Nilasis Chaudhuri

We study the Euler--Riesz system on the torus , : the compressible Euler equations with barotropic pressure (, ), coupled to…

Homogenization of compressible Navier-Stokes equations under a hard sphere pressure law

Nilasis Chaudhuri, Florian Oschmann

We consider the compressible time-dependent Navier-Stokes equations in a bounded perforated domain in dimensions two and three. Provided the perforations are small enough, we show…

Anelastic approximation for the degenerate compressible Navier--Stokes equations revisited

Nilasis Chaudhuri, Francesco Fanelli, Yang Li +1

In this paper, we revisit the joint low-Mach and low-Frode number limit for the compressible Navier-Stokes equations with degenerate, density-dependent viscosity. Employing the rel…

Regular solutions to the dissipative Aw-Rascle system

Nilasis Chaudhuri, Tomasz Piasecki, Ewelina Zatorska

In this paper we prove the local-in-time existence of regular solutions to dissipative Aw-Rascle system with the offset equal to gradient of some increasing and regular function of…
