Sharp lower bounds for the periodic maximal Schrödinger operator in higher dimensions

Inbo Gottlieb Fenves, Jiahao Tan

We prove sharp lower bounds for the Schrödinger maximal function on the torus T^d for all dimensions d at least 2, and as a corollary obtain sharp regularity conditions for pointwi…

Maximal estimates for perturbations of the Schrödinger operator on $T^{d}$

Inbo Gottlieb Fenves, Jiahao Tan

We study $L_{x}^{p} L_{t}^{\infty}$ maximal estimates for exponential sums associated to $C^{2}$ graph hypersurfaces, motivated by Schrödinger maximal estimates on $T^{d}$ . We show th…
