摘要	A surface Sigma is a graph in R-4 if there is a unit constant 2-form w on R 4 such that (e(1) boolean AND e(2), w) greater than or equal to v(0) > 0 where (e(1), e(2)) is an orthonormal frame on Sigma. We prove that, if v(0) greater than or equal to 1/root2 on the initial surface, then the mean curvature flow has a global solution and the scaled surfaces converge to a self-similar solution. A surface Sigma is a graph in M-1 x M-2 where M-1 and M-2 are Riemann surfaces, if (e(1) boolean AND e(2), w(1)) greater than or equal to v(0) > 0 where w(1) is a Kahler form on M-1. We prove that, if M is a Kahler-Einstein surface with scalar curvature R, v(0) greater than or equal to 1/root2 on the initial surface, then the mean curvature flow has a global solution and it sub-converges to a minimal surface, if, in addition, R greater than or equal to 0 it converges to a totally geodesic surface which is holomorphic.
