Generalised Fisher Information in Defective Fokker-Planck Equations
Anton Arnold, Amit Einav, Tobias Wöhrer
The goal of this work is to introduce and investigate a generalised Fisher Information in the setting of linear Fokker-Planck equations. This functional, which depends on two funct…

Convergence to equilibrium for a degenerate McKean-Vlasov Equation
Manh Hong Duong, Amit Einav
In this work we study the convergence to equilibrium for a (potentially) degenerate nonlinear and nonlocal McKean-Vlasov equation. We show that the solution to this equation is rel…
