主 题：Absolutely continuous spectrum of multi-frequency Quasiperiodic Schrodinger operator
内容简介：We prove that for any d-frequency analytic quasiperiodic Schrodinger operator, if the frequency is weak Liouvillean, and the potential is small enough, then thecorresponding operator has absolutely continuous spectrum. If d=2, we establish the existence of ac spectrum under small potential and some super-liouvillean frequency, which is optimal due to recent counterexample of Avila and Jitomirskaya.
