报告摘要
We exploit various structures of dual cocycles and develop several new concepts and tools for the study of one-frequency quasiperiodic operators with analytic potentials. As applications we solve three long-standing arithmetic conjectures: the ten martini problem, sharp phase transition in frequency and absolute continuity of the integrated density of states for all frequencies for the entire class of type I operators.
