Regularity of finite-dimensional realizations for Evolution Equations
Damir Filipovic, Josef Teichmann
We show that a continuous local semiflow of -maps on a finite-dimensional -manifold M can be embedded into a local -flow on M under some weak (necessary) assumptions…
Smooth perfectness through decomposition of diffeomorphisms into fiber preserving ones
Stefan Haller, Josef Teichmann
We show that on a closed smooth manifold equipped with fiber bundle structures whose vertical distributions span the tangent bundle, every smooth diffeomorphism of …
Finite dimensional Realizations of Stochastic Equations
Damir Filipovic, Josef Teichmann
This paper discusses finite-dimensional (Markovian) realizations (FDRs) for Heath-Jarrow-Morton interest rate models. We consider a d-dimensional driving Brownian motion and stocha…
Totally geodesic subgroups of diffeomorphisms
Stefan Haller, Josef Teichmann, Cornelia Vizman
We determine the Riemannian manifolds for which the group of exact volume preserving diffeomorphisms is a totally geodesic subgroup of the group of volume preserving diffeomorphism…
