Invariant sets and long time behaviour of operator semigroups
(Universität Ulm, 2017-02-10)
In this PhD thesis, strongly continuous operator semigroups are studied. We show that contractivity or positivity of such a semigroup can have a profound impact on its long time behaviour. Moreover, we perform a detailed ...
Second order parabolic equations with non-local boundary conditions on L∞(Ω) and C(Ω̅): generation, regularity and asymptotics
(Universität Ulm, 2017-07-05)
The aim of the present thesis is to analyze second order parabolic equations with non-local boundary conditions of Dirichlet and Robin type on the spaces L∞(Ω) and C(Ω̅). We will prove well-posedness of such equations and ...
The principle of linearised stability for non-linear parabolic Volterra equations
(Universität Ulm, 2018-07-12)
This thesis is concerned with the long-time behaviour of solutions to non-linear abstract parabolic Volterra equations. The focus is both on a wide class of semilinear parabolic Volterra equations and on quasilinear ...

Adding randomness to nonlinear semigroups: existence, uniqueness and asymptotic results
(Universität Ulm, 2018-11-15)
The origins of this thesis lie in the present author’s study of the asymptotic behavior of the weighted p-Laplacian evolution equation, which is one of the bench marks of nonlinear evolution equations and used to model ...
