It is shown that control of the Schrödinger maximal function sup0 <t<1 ǀeitΔfǀ for f ∈ Hs(Rn) requires s ≥ n/2(n + 1). 
A sharp Schrödinger maximal estimate in R[superscript 2]
We show that limt→0 eit∆f(x) = f(x) almost everywhere for all f ∈ Hs(R2) provided that s > 1/3. This result is sharp up to the endpoint. The proof uses polynomial partitioning and decoupling.
Lower bounds for estimates of the Schrödinger maximal function
We give new lower bounds for $L^p$ estimates of the Schr\"odinger maximal function by generalizing an example of Bourgain.

Abstract We consider Carleson's problem regarding pointwise convergence for the Schrödinger equation. Bourgain proved that there is initial data, in Hs(ℝn) with $s<\frac{n}{2(n+1)}$, for which the
A Note on the Refined Strichartz Estimates and Maximal Extension Operator
There are two parts for this paper. In the first part we extend the refined Strichartz estimates to hypersurfaces with nonzero Gaussian curvature. In the second part we prove some positive results
Note on maximal estimates of generalized Schrödinger equation
In this study we extend the recent works on the pointwise convergence for the solutions of Schr\"odinger equations based on Du, Guth, and Li and Du and Zhang to generalized Schr\"odinger equations.
Convergence of sequences of Schr\"odinger means.
We study convergence almost everywhere of sequences of Schrodinger means. We also replace sequences by uncountable sets.
Pointwise convergence along a tangential curve for the fractional Schrödinger equation with 0 < m < 1
In this article, we study the pointwise convergence problem about solution to the fractional Schrödinger equation with 0 < m < 1 along a tangential curve and estimate the capacitary dimension of the
A sharp Schrodinger maximal estimate in $\mathbb{R}^2$
We show that $\lim_{t \to 0} e^{it\Delta}f(x) = f(x)$ almost everywhere for all $f \in H^s (\mathbb{R}^2)$ provided that $s>1/3$. This result is sharp up to the endpoint. The proof uses polynomial
