In this paper, we shall define a new concept, P map. Therefore the question which arises in will be answered satisfactorily, i.e. a frame map f: K→L from a T 2 frame K to a T 2 frame L can be uniquely extended to a frame map τf:τK→τL if and only if f is a P map. 展开更多

We obtain the global weighted estimates for Jacobian J(x,f) and its subdeterminants, as well as the components of K-quasiconformal mappings in L^p (μ)-averaging domains. To develop these estimates, both local and global weighted Ponincaré inequalities for differential forms are established. 展开更多

We establish a new type of the classical boundary Schwarz lemma for holomorphic self-mappings of the unit polydisk Dnin Cn. By using the Carath′eodory metric and Kobayashi metric of Dn, we obtain some properties of the complex Jacobian matrix Jf(p) at a boundary point p of Dnfor a holomorphic self-mapping f of Dn. Our results extend the classical Schwarz lemma at the boundary to high dimensions. 展开更多

This paper deals with the p-harmonic function on a complete non-compact submanifold M isometrically immersed in an(n + k)-dimensional complete Riemannian manifold M of non-negative(n-1)-th Ricci curvature. The Liouville type theorem about the p-harmonic map with finite L^q-energy from complete submanifold in a partially nonnegatively curved manifold to non-positively curved manifold is also obtained. 展开更多
