The Kohn-Laplacian and Cauchy-Szegö projection on Model Domains
Der-Chen Chang, Ji Li, Jingzhi Tie +1
We study the Kohn-Laplacian and its fundamental solution on some model domains in , and further discuss the explicit kernel of the Cauchy-Szegö projections on thes…
Gradient Shrinking Sasaki-Ricci Solitons on Sasakian Manifolds of Dimension Up to Seven
Der-Chen Chang, Shu-Cheng Chang, Yingbo Han +2
In this paper, we show that the uniform L^4-bound of the transverse Ricci curvature along the Sasaki-Ricci flow on a compact quasi-regular transverse Fano Sasakian (2n+1)-manifold…
Fundamental properties of Cauchy--Szegő projection on quaternionic Siegel upper half space and applications
Der-Chen Chang, Xuan Thinh Duong, Ji Li +2
We investigate the Cauchy--Szegő projection for quaternionic Siegel upper half space to obtain the pointwise (higher order) regularity estimates for Cauchy--Szegő kernel and prove…
Nontriviality of Riesz--Morrey Spaces
Zongze Zeng, Der-Chen Chang, Tao +1
In this article, the authors completely answer an open question, presented in [Banach J. Math. Anal. 15 (2021), no. 1, 20], via showing that the Riesz--Morrey space is truly a new…
Littlewood-Paley Characterizations of Hardy-type Spaces Associated with Ball Quasi-Banach Function Spaces
Der-Chen Chang, Songbai Wang, Dachun Yang +1
Let be a ball quasi-Banach function space on . In this article, assuming that the powered Hardy--Littlewood maximal operator satisfies some Fefferman--Stein vect…
An explicit formula of Cauchy--Szegö kernel for quaternionic Siegel upper half space and applications
Der-Chen Chang, Xuan Thinh Duong, Ji Li +2
In this paper we obtain an explicit formula of Cauchy--Szegö kernel for quaternionic Siegel upper half space, and then based on this, we prove that the Cauchy--Szegö projection on…
