报告题目：Global rigidity results for ultra-differentiable quasiperiodic  cocycles

报告摘要：In this talk, we show that for a large class of ultra-differentiable potential, and for any irrational frequency,  for almost every energy  the corresponding quasiperiodic Schrodinger cocycle is either rotations reducible or has positive Lyapunov exponents. This partially answers R. Krikorian's open question.  As spectral application, we prove ``Last's intersection spectrum conjecture in the Gevrey setting.
