报告摘要:In this talk, we consider maps from pseudo-Hermitian manifolds to Käler manifolds and introduce partial energy functionals for these maps. First, we obtain a foliated Lichnerowicz type result on general pseudo- Hermitian manifolds. Next, we investigate critical maps of the partial energy functionals, which are referred to as dbarb-harmonic maps and db- harmonic maps. We give a foliated result for both dbarb- and db-harmonic maps, generalizing a foliated result of Petit for harmonic maps. Then we are able to generalize Siu’s holomorphicity result for harmonic maps to the case for dbarb- and db-harmonic maps. This is a joint work with Hui Liu and Biqiang Zhao.
