A Structural Observation on port-Hamiltonian Systems

Rainer Picard, Sascha Trostorff, Bruce Watson +1

We study port-Hamiltonian systems on a familiy of intervals and characterise all boundary conditions leading to -accretive realisations of the port-Hamiltonian operator and thus…

Dynamic First Order Wave Systems with Drift Term on Riemannian Manifolds

Rainer Picard, Sascha Trostorff

An abstract first order differential equation of hyperbolic type with drift term on a Riemannian manifold is considered. For proving its well-posedness, transmutator and commutator…

A Hilbert space approach to fractional differential equations

Kai Diethelm, Konrad Kitzing, Rainer Picard +3

We study fractional differential equations of Riemann-Liouville and Caputo type in Hilbert spaces. Using exponentially weighted spaces of functions defined on , we defi…

On a Class of Degenerate Abstract Parabolic Problems and Applications to Some Eddy Current Models

Dirk Pauly, Rainer Picard, Sascha Trostorff +1

We present an abstract framework for parabolic type equations which possibly degenerate on certain spatial regions. The degeneracies are such that the equations under investigation…

A Hilbert space approach to difference equations

Konrad Kitzing, Rainer Picard, Stefan Siegmund +2

We consider general difference equations for on exponentially weighted spaces of two-sided Hilbert space valued sequences and dis…

On the Well-posedness of a Class of Non-Autonomous SPDEs: An Operator-Theoretical Perspective

Rainer Picard, Sascha Trostorff, Marcus Waurick

We further elaborate on the solvability of stochastic partial differential equations (SPDEs). We shall discuss non-autonomous partial differential equations with an abstract realiz…
