摘要本文研究了一类具有实解析相位的一维振荡积分算子的锐阻尼估计。通过建立适当阻尼的振荡积分算子的端点估计,我们能够给出尖锐Lp {L^{p}}估计的新证明,这些估计已由Xiao在[Endpointestimates for one-dimensional oscillating integral operators,Adv. Math. 316 2017,255-291]中证明。本文得到的阻尼估计是独立的。
Abstract In this paper, we investigate sharp damping estimates for a class of one-dimensional oscillatory integral operators with real-analytic phases. By establishing endpoint estimates for suitably damped oscillatory integral operators, we are able to give a new proof of the sharp L p {L^{p}} estimates, which have been proved by Xiao in [Endpoint estimates for one-dimensional oscillatory integral operators, Adv. Math. 316 2017, 255–291]. The damping estimates obtained in this paper are of independent interest.
