Abstract In this paper, we establish an improved variable coefficient version of the square function inequality, by which the local smoothing estimate L α p → L p {L^{p}_{\alpha}\to L^{p}} for the Fourier integral operators satisfying cinematic curvature condition is further improved. In particular, we establish almost sharp results for 2 < p ⩽ 3 {2

一类满足电影曲率条件的傅立叶积分算子的平方函数不等式

摘要 在本文中,我们建立了平方函数不等式的改进变系数版本,由此局部平滑估计 L α p → L p {L^{p}_{\alpha}\to L^{p}} 为进一步改进了满足电影曲率条件的傅立叶积分算子。特别是,我们为 2 < p ⩽ 3 {2
