On efficiency and localisation for the torsion function
M. van den Berg, D. Bucur, T. Kappeler
We consider the torsion function for the Dirichlet Laplacian , and for the Schrödinger operator on an open set of finite Lebesgue measure $0<|Ω|<\infty…
On nomalized differentials on spectral curves associated to thesinh-Gordon equation
Thomas Kappeler, Yannick Widmer
The spectral curve associated with the sinh-Gordon equation on the torus is defined interms of the spectrum of the Lax operator appearing in the Lax pair formulation of the equatio…
On normalized differentials on hyperelliptic curves of infinite genus
T. Kappeler, P. Topalov
We develop a new approach for constructing normalized differentials on hyperelliptic curves of infinite genus and obtain uniform asymptotic estimates for the distribution of their…
Interpolation of nonlinear maps
T. Kappeler, A. Savchuk, A. Shkalikov +1
Let and be complex Banach couples and assume that with norms satisfying for some . For any $0<θ<1…
From Toda to KdV
Dario Bambusi, Thomas Kappeler, Thierry Paul
For periodic Toda chains with a large number of particles we consider states which are -close to the equilibrium and constructed by discretizing arbitrary given f…
Isospectrality and heat content
M. van den Berg, E. B. Dryden, T. Kappeler
We present examples of isospectral operators that do not have the same heat content. Several of these examples are planar polygons that are isospectral for the Laplace operator wit…
