Rates of convergence to equilibrium for collisionless kinetic equations in slab geometry
Mustapha Mokhtar-Kharroubi, David Seifert
This work deals with free transport equations with partly diffuse stochastic boundary operators in slab geometry. Such equations are governed by stochastic semigroups in sp…
Optimal rates of decay for operator semigroups on Hilbert spaces
Jan Rozendaal, David Seifert, Reinhard Stahn
We investigate rates of decay for -semigroups on Hilbert spaces under assumptions on the resolvent growth of the semigroup generator. Our main results show that one obtains th…
Non-optimality of the Greedy Algorithm for subspace orderings in the method of alternating projections
Oscar Darwin, Aashraya Jha, Souktik Roy +3
The method of alternating projections involves projecting an element of a Hilbert space cyclically onto a collection of closed subspaces. It is known that the resulting sequence al…
Quantified asymptotic behaviour of Banach space operators and applications to iterative projection methods
Catalin Badea, David Seifert
We present an extension of our earlier work [Ritt operators and convergence in the method of alternating projections, J. Approx. Theory, 205:133-148, 2016] by proving a general asy…
Asymptotics for periodic systems
Lassi Paunonen, David Seifert
This paper investigates the asymptotic behaviour of solutions of periodic evolution equations. Starting with a general result concerning the quantified asymptotic behaviour of peri…
