Scattering operator and wave operators for 2D Schrödinger operators with threshold obstructions
Serge Richard, Rafael Tiedra de Aldecoa, Lyang Zhang
We determine the low-energy behaviour of the scattering operator of two-dimensional Schrödinger operators with any type of obstructions at 0-energy. We also derive explicit formula…
Ruled strips with asymptotically diverging twisting
David Krejcirik, Rafael Tiedra de Aldecoa
We consider the Dirichlet Laplacian in a two-dimensional strip composed of segments translated along a straight line with respect to a rotation angle with velocity diverging at inf…
Furstenberg transformations on Cartesian products of infinite-dimensional tori
P. A. Cecchi, R. Tiedra de Aldecoa
We consider in this note Furstenberg transformations on Cartesian products of infinite-dimensional tori. Under some appropriate assumptions, we show that these transformations are…
New formulae for the wave operators for a rank one interaction
Serge Richard, Rafael Tiedra de Aldecoa
We prove new formulae for the wave operators for a Friedrichs scattering system with a rank one perturbation, and we derive a topological version of Levinson's theorem for this mod…
