主  題：Absolutely continuous spectrum of multi-frequency Quasiperiodic Schrodinger operator

內(nèi)容簡(jiǎn)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.
