Quasi-Periodic Schrödinger Cocycles with Positive Lyapunov Exponent are not Open in the Smooth Topology
Yiqian Wang, Jiangong You
One knows that the set of quasi-periodic Schrödinger cocycles with positive Lyapunov exponent is open and dense in the analytic topology. In this paper, we construct cocycles with…

Cantor spectrum for a class of quasiperiodic Schrödinger operators
Yiqian Wang, Zhenghe Zhang
We show that for a class of quasiperiodic potentials and for any Diophantine frequency, the spectrum of the corresponding Schrödinger operators is Cantor. Our approach is of…
