报告题目:The non-existence of wave operators for the fractional Schrödinger operators
报告摘要:I will introduce a class of decaying potentials, for which the wave operators associated to the fractionalSchrödinger operator,do not exist. The result is in the full range, and the decay rate is sharp by the recent work on the existence side. In particular, this gives a new threshold for a potential to have short range, where the decay assumption is faster than the usual accepted Coulomb decay.
