About me
I am currently a third year Ph.D student in Department of Mathematics at University of Wisconsin-Madison. I am working with Shaoming Guo. My research interests lie in harmonic analysis. Especially, I am interested in restriction estimates, decoupling inequalities, and their applications.
Papers
Decoupling inequalities for quadratic forms (with S. Guo, R. Zhang, P. Zorin-Kranich). Preprint.
Fourier restriction estimates for surfaces of co-dimension two in R^5 (with S. Guo). Preprint.
A restriction estimate for surfaces with negative Gaussian curvatures (with S. Guo). Preprint.
Decoupling for two quadratic forms in three variables: a complete characterization (with S. Guo, J. Roos, P.-L. Yung, P. Zorin-Kranich). Preprint.
Small cap decoupling inequalities: Bilinear methods. To appear in Rev. Mat. Iberoam.
