Abstract

In this paper, we study the Lagrangian F-stability and Hamiltonian F-stability of Lagrangian self-shrinkers. We prove a characterization theorem for the Hamiltonian F-stability of nn-dimensional complete Lagrangian self-shrinkers without boundary, with polynomial volume growth and with the second fundamental form satisfying the condition that there exist constants C0>0C_0>0 and ε<116n\varepsilon<\frac{1}{16n} such that A2C0+εx2|A|^2\leq C_0+\varepsilon |x|^2. We characterize the Hamiltonian F-stablity by the eigenvalues and eigenspaces of the drifted Laplacian.

v1: 20 pages; v2: 21 pages, we weakened our condition on the second fundamental norm in this version; v3: 21 pages, revised (9.17), and corresponding minor changes in the last section
