Abstract

Let Fn:(Σ,hn)C2F_n :(\Sigma, h_n) \to \mathbb C^2 be a sequence of conformally immersed Lagrangian self-shrinkers with a uniform area upper bound to the mean curvature flow, and suppose that the sequence of metrics {hn}\{h_n\} converges smoothly to a Riemannian metric hh. We show that a subsequence of {Fn}\{F_n\} converges smoothly to a branched conformally immersed Lagrangian self-shrinker F:(Σ,h)C2F_\infty : (\Sigma, h)\to \mathbb C^2. When the area bound is less than 16π16\pi, the limit FF_\infty is an embedded torus. When the genus of Σ\Sigma is one, we can drop the assumption on convergence hnhh_n\to h. When the genus of Σ\Sigma is zero, we show that there is no branched immersion of Σ\Sigma as a Lagrangian shrinker, generalizing the rigidity result of Smoczyk in dimension two by allowing branch points.
