讲座简介:
In this talk, we investigate pseudoharmonic maps from the pseudo-Hermitian manifolds. We first give the CR Bochner type result for pseudoharmonic maps. Then some foliated results, pluriharmonicity and Siu-Sampson type results are established for pseudoharmonic maps. Finally, we use the heat flow method to prove the existence of pseudoharmonic maps from closed pseudo-Hermitian manifolds. It is a generalization of Eells-Sampson’s existence theorem. We also get the Hartman’s type theorem.
