Delocalization for the 3-D discrete random Schroedinger operator at weak disorder
Westin King, Robert C. Kirby, Constanze Liaw
We apply a recently developed approach (Liaw 2013) to study the existence of extended states for the three dimensional discrete random Schroedinger operator at small disorder. The…
Cyclicity in Dirichlet-type spaces and extremal polynomials II: functions on the bidisk
Catherine Bénéteau, Alberto A. Condori, Constanze Liaw +2
We study Dirichlet-type spaces of analytic functions in the unit bidisk and their cyclic elements. These are the functions for which there exists a sequence $(…
Clark model in general situation
Constanze Liaw, Sergei Treil
For a unitary operator the family of its unitary perturbations by rank one operators with fixed range is parametrized by a complex parameter . Namely all such unitary per…
Cyclicity in Dirichlet-type spaces and extremal polynomials
Catherine Bénéteau, Alberto Condori, Constanze Liaw +2
For functions in Dirichlet-type spaces we study how to determine constructively optimal polynomials that minimize among all polynomials of degree at mos…
