Steady states of the spherically symmetric Vlasov-Poisson system as fixed points of a mass-preserving algorithm
Håkan Andréasson, Markus Kunze, Gerhard Rein
We give a new proof for the existence of spherically symmetric steady states to the Vlasov-Poisson system, following a strategy that has been used successfully to approximate axial…

Quantitative phase mixing for Hamiltonians with trapping
Mahir HadžiÄ, Gerhard Rein, Matthew Schrecker +1
We prove quantitative decay estimates of macroscopic quantities generated by the solutions to linear transport equations driven by a general family of Hamiltonians. The associated…
