复时Schr dinger型极大算子的有界性

Boundedness of Maximal Operators of Schrödinger Type with Complex Time

Andrew D. Bailey

摘要:

Sjölin和F. Soria的薛定谔极大算子与复值时间的改进通过确定到端点的尖锐$s \geq 0$从索伯列夫空间$H^s(\mathbb{R})$到$L^2(\mathbb{R})$发生有界性。不仅建立了薛定谔极大算子的界,而且进一步建立了与某些色散偏微分方程的解算子相对应的一般类极大算子的界。由于这些最大的运营商从$H^s(\mathbb{R})$到$L^2([-1, 1])$的额外的界限,尖锐的结果上的逐点几乎处处收敛这些偏微分方程的解决方案,其初始数据被确定。

英文摘要:

Results of P. Sjölin and F. Soria on the Schrödinger maximal operator with complex-valued time are improved by determining up to the endpoint the sharp $s \geq 0$ for which boundedness from the Sobolev space $H^s(\mathbb{R})$ into $L^2(\mathbb{R})$ occurs. Bounds are established for not only the Schrödinger maximal operator, but further for a general class of maximal operators corresponding to solution operators for certain dispersive PDEs. As a consequence of additional bounds on these maximal operators from $H^s(\mathbb{R})$ into $L^2([-1, 1])$, sharp results on the pointwise almost everywhere convergence of the solutions of these PDEs to their initial data are determined.
