摘要

In this talk, we first derive a CR version of Bochner identity for the pseudoharmonic map heat flow on pseudohermitian manifolds. Secondly, we are able to prove the existence of global solution for the pseudoharmonic map heat flow from a closed pseudohermitian manifold into a Riemannian manifold with non-positive sectional curvature. In particular, we prove the existence theorem of pseudoharmonic maps. This is served as the CR analogue of Eell-Sampson’s theorem for the harmonic map heat flow.
