Sparse domination and $L^{p} \to L^{q}$ estimates for maximal functions associated with curvature

Wenjuan Li, Huiju Wang, Yujia Zhai

In this paper, we study maximal functions along some finite type curves and hypersurfaces. In particular, various impacts of non-isotropic dilations are considered. Firstly, we pro…

Sharp convergence for sequences of nonelliptic Schrödinger means

Wenjuan Li, Huiju Wang, Dunyan Yan

We consider pointwise convergence of nonelliptic Schrödinger means $e^{i t_{n} □} f (x)$ for $f \in H^{s} (R^{2})$ and decreasing sequences ${t_{n}}_{n = 1}^{\infty}$ con…

Pointwise Convergence for sequences of Schrödinger means in $R^{2}$

Wenjuan Li, Huiju Wang, Dunyan Yan

We consider pointwise convergence of Schrödinger means $e^{i t_{n} Δ} f (x)$ for $f \in H^{s} (R^{2})$ and decreasing sequences ${t_{n}}_{n = 1}^{\infty}$ converging to zero. T…

$L^{p} \to L^{q}$ estimates for maximal functions associated with nonisotropic dilations of hypersurfaces in $R^{3}$

Wenjuan Li, Huiju Wang

The goal of this article is to establish $L^{p} \to L^{q}$ estimates for maximal functions associated with nonisotropic dilations $δ_t(x)=(t^{a_1}x_1,t^{a_2}x_2,t^{a_3}x_3)…

Pointwise convergence of solutions to the Schrödinger equation along a class of curves

Wenjuan Li, Huiju Wang

In this paper, we obtain pointwise convergence of solutions to the Schrodinger equation along a class of curves in $R^{2}$ by the polynomial partitioning.

Weighted Caffarelli-Kohn-Nirenberg type inequalities related to Grushin type operators

Manli Song, Wenjuan Li

We consider the Grushin type operator on $R_{x}^{d} \times R_{y}^{k}$ with the form \begin{equation*} G_μ=\overset{d}{\underset{i=1}{\sum}}\partial_{x_i}^2+\left(\ove…
