Control for Schroedinger operators on tori
نویسندگان
چکیده
A well known result of Jaffard states that an arbitrary region on a torus controls , in the L 2 sense, solutions of the free stationary and dynamical Schrödinger equations. In this note we show that the same result is valid in the presence of a potential, that is for Schrödinger operators, −∆ + V , V ∈ C ∞ .

Fluctuation based proof of the stability of ac spectra of random operators on tree graphs
The talk will summarize recent works on the stability under disorder of the absolutely continuous spectra of random operators on tree graphs. The cases covered include: Schroedinger operators with random potential, quantum graph operators for trees with randomized edge lengths, and Schroedinger operators with radial quasi-periodic potentials. The results were derived jointly with R. Sims and S....

Random Schroedinger operators with connections to spectral properties of groups and directed polymers Marcin Kotowski Doctor of Philosophy Graduate Department of Mathematics University of Toronto 2016 This thesis studies random Schroedinger operators with connections to group theory and models from statistical physics. First, we study 1D operators obtained as perturbations of the standard adjac...
متن کاملRenormalization for breakup of invariant tori
We present renormalization group operators for the breakup of invariant tori with winding numbers that are quadratic irrationals. We find the simple fixed points of these operators and interpret the map pairs with critical invariant tori as critical fixed points. Coordinate transformations on the space of maps relate these fixed points, and also induce conjugacies between the corresponding oper...

متن کاملAnalyticity for Second Order Operators Constructed from Rigid Vector Fields on Products of Tori
We prove global analytic hypoellipticity on a product of tori for partial differential operators which are constructed as rigid (variable coefficient) quadratic polynomials in real vector fields satisfying the Hörmander condition and where P satisfies a ‘maximal’ estimate. We also prove an analyticity result that is local in some variables and global in others for operators whose prototype is P...
