报告摘要:
In this talk we will discuss almost everywhere convergence of Bochner-Riesz means for the Hermite operator H = −∆+ |x|2 in Rn . Surprisingly, for the dimensions n ≥2 our result reduces the borderline summability index for a.e. convergence for f∈Lp(R) with p ≥2 as small as only half of the critical index required for a.e. convergence of the classical Bochner-Riesz means for the Laplacian. When n = 1, we show a.e. convergence holds for f∈Lp(R) with p ≥2 whenever λ> 0. Compared with the classical result due to Askey and Wainger, we only need smaller summability index for a.e. convergence. This is a joint work with P. Chen, X.T. Duong, D.Q. He and S. Lee.
