In this paper, we first set up an alternative fundamental theory of M?bius geometry for any umbilic-free spacelike hypersurfaces in four dimensional Lorentzian space form, and prove the hypersurfaces can be determined...

In this paper, we discuss the Schatten-p class (0 〈 p≤∞ ) of Toeplitz operators on generalized Foek space with the symbol in positive Borel measure. It makes a great difference from other papers by using the esti...

Let Mn be an n-dimensional submanifold without umbilical points in the (n + 1)-dimen- sional unit sphere Sn+l. Four basic invariants of Mn under the Moebius transformation group of Sn+1 are a 1-form Ф called moe...

We consider the scattering of Cauchy problem for the focusing combined power-type Schroodinger equation. In the spirit of concentration-compactness method, we will show that, H1 solution will scatter under some condit...

Let M be a simple manifold, and F be a component of δM of genus two. For a slope γ on F, we denote by M(γ) the manifold obtained by attaching a 2-handle to M along a regular neighborhood of γon F. In this paper,...
