报告摘要：It was well-known that the $L^p$ decay estimates of Schrödinger operators, is a widely studied topic, which plays an important role in the well-posedness of nonlinear dispersive equations and the long time (asymptotic) stability of solitary waves. In this talk, I will review some recent works on the time decay estimates of the higher order elliptic operators (poly-harmonic type) with the decay potentials. The main techniques based on the detailed analysis of free resolvent and spectral perturbation, where the classifications of zero resonances and zero asymptotic expansions of resolvent are the most important parts, which are indispensable to establish all kinds of dispersive results with general potentials.
