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 E 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.
