Outline of Final Research Achievements

We generalize the maximum principle due to Omori and Yau for Laplacian to L operator on complete self-shrinkers of mean curvature flow. Making use of this generalized maximum principle for L operator, we study complete self-shrinkers of mean curvature and give a complete classification for 2-dimensional complete self-shrinkers in the 3-dimensional Euclidean space. Furthermore, for complete self-shrinkers of mean curvature flow with polynomial area growth, we get the second pinching constant of the constant length of the second fundamental form. We also prove a universal inequality on eigenvalues of L operator in complete self-shrinkers. According to this universal inequality, we obtain an upper bound and a lower bound of eigenvalues for L operator in complete self-shrinkers.
