Fluctuation based proof of the stability of ac spectra of random operators on tree graphs
نویسنده
چکیده
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. Warzel.

Persistence under Weak Disorder of AC Spectra of Quasi-Periodic Schrödinger operators on Trees Graphs
We consider radial tree extensions of one-dimensional quasi-periodic Schrödinger operators and establish the stability of their absolutely continuous spectra under weak but extensive perturbations by a random potential. The sufficiency criterion for that is the existence of Bloch-Floquet states for the one dimensional operator corresponding to the radial problem.
متن کاملStability of the Absolutely Continuous Spectrum of Random Schrödinger Operators on Tree Graphs
The subject of this work are random Schrödinger operators on regular rooted tree graphs T with stochastically homogeneous disorder. The operators are of the form Hλ(ω) = T + U + λV (ω) acting in l(T), with T the adjacency matrix, U a radially periodic potential, and V (ω) a random potential. This includes the only class of homogeneously random operators for which it was proven that the spectrum...

This short note points out an improvement on the robust stability analysis for electrically driven robots given in the paper. In the paper, the author presents a FAT-based direct adaptive control scheme for electrically driven robots in presence of nonlinearities associated with actuator input constraints. However, he offers not suitable stability analysis for the closed-loop system. In other w...
