标题:Parametrized KAM scheme and almost reducibility of quasi-periodic linear systems


报告人:赵之彦 (法国尼斯大学)


摘要:For the quasi-periodic sl(2,\R) linear systems, we review the parametrized KAM scheme given by Eliasson in 1992.Reducibility and almost reducibility of the system are shown via this KAM scheme. As applications,properties related to absolutely continuous spectrum, such as ballistic transport and dispersion,can be shown for the time evolution of the corresponding quasi-periodic self-adjoint operator.
