Existence of nonconstant CR-holomorphic functions of polynomial growth in Sasakian Manifolds
Shu-Cheng Chang, Yingbo Han, Nan Li +1
In this paper, we show that there exists a nonconstant CR holomorphic function of polynomial growth in a complete noncompact Sasakian manifold of nonnegative pseudohermitian bisect…
On the Obata Theorem in a weighted Sasakian manifold
Shu-Cheng Chang, Daguang Chen, Chin-Tung Wu
In this paper, we generalize the CR Obata theorem to a compact strictly pseudoconvex CR manifold with a weighted volume measure. More precisely, we first derive the weighted CR Rei…
On the CR analogue of Frankel conjecture and a smooth representative of the first Kohn-Rossi cohomology group
Der-Chen Chang, Shu-Cheng Chang, Ting-Jung Kuo +1
In this note, we first give a criterion of pseudo-Einstein contact forms and then affirm the CR analogue of Frankel conjecture in a closed, spherical, strictly pseudoconvex CR mani…
Global existence and convergence for the CR Q-curvature flow in a closed strictly pseudoconvex CR 3-manifold
Shu-Cheng Chang, Ting-Jung Kuo, Takanari Saotome
In this note, we affirm the partial answer to the long open Conjecture which states that any closed embeddable strictly pseudoconvex CR -manifold admits a contact form with…
-positivity and a classification of closed three-dimensional CR torsion solitons
Huai-Dong Cao, Shu-Cheng Chang, Chih-Wei Chen
A closed CR 3-manifold is said to have -positive pseudohermitian curvature if for any . We discover an obstruction for a closed…
