Asymptotics of spectral quantities of Schrödinger operators
T. Kappeler, B. Schaad, P. Topalov
In this paper we provide new asymptotic estimates of the Floquet exponents of Schrödinger operators on the circle. By the same techniques, known asymptotic estimates of various oth…

On the regularity of the composition of diffeomorphisms
Hasan Inci, Thomas Kappeler, Peter Topalov
For being a closed manifold or the Euclidean space we present a detailed proof of regularity properties of the composition of -regular diffeomorphisms of for $s > 1/2\…

On the Space of Trajectories of a Generic Vector Field
Dan Burghelea, Leonid Friedlander, Thomas Kappeler
This paper describes the construction of a canonical compactification of the space of trajectories and of the unstable/stable sets of a generic gradient like vector field on a clos…
