Localised Relative Energy and Finite Speed of Propagation for Compressible Flows
Emil Wiedemann
For the incompressible and the isentropic compressible Euler equations in arbitrary space dimension, we establish the principle of localised relative energy, thus generalising the…

Weak-strong uniqueness in fluid dynamics
Emil Wiedemann
We give a survey of recent results on weak-strong uniqueness for compressible and incompressible Euler and Navier-Stokes equations, and also make some new observations. The importa…

Generalized Entropy Method for the Renewal Equation with Measure Data
Piotr Gwiazda, Emil Wiedemann
We study the long-time asymptotics for the so-called McKendrick-Von Foerster or renewal equation, a simple model frequently considered in structured population dynamics. In contras…
