This review paper is concerned with the stability analysis of the continuity equation in the DiPerna–Lions setting in which the advecting velocity field is Sobolev regular. Quantitative estimates for the equation were derived only recently, but optimality was not discussed. We revisit the results from our 2017 paper, compare the new estimates with previously known estimates for Lagrangian flows and demonstrate how these can be applied to produce optimal bounds in applications from physics…

Optimal stability estimates and a new uniqueness result for advection-diffusion equations
This paper contains two main contributions. First, it provides optimal stability estimates for advection-diffusion equations in a setting in which the velocity field is Sobolev regular in the spatial…

Quantitative Regularity Estimates for Compressible Transport Equations
These notes aim at presenting some recent estimates for transport equations with rough, i.e., non-smooth, velocity fields. Our final goal is to use those estimates to obtain new results on complex…
Advection Diffusion Equations with Sobolev Velocity Field
In this note we study advection diffusion equations associated to incompressible $W^{1,p}$ velocity fields with $p>2$. We present new estimates on the energy dissipation rate and we discuss…
Convergence Rates for Upwind Schemes with Rough Coefficients
TLDR
The case where the advecting velocity field has spatial Sobolev regularity and initial data are merely integrable is interested, and the rate of weak convergence is at least 1/2 in the mesh size.
Error estimates for a finite volume scheme for advection-diffusion equations with rough coefficients
We study the implicit upwind finite volume scheme for numerically approximating the advection-diffusion equation with a vector field in the low regularity DiPerna-Lions setting. That is, we are…

TLDR
It is proved that on unstructured regular meshes the rate of convergence of approximate solutions generated by the upwind scheme towards the unique distributional solution of the continuous model is at least 1/2.

Abstract We consider the inviscid limit for the two-dimensional Navier–Stokes equations in the class of integrable and bounded vorticity fields. It is expected that the difference between the…
