Evolution by mean curvature flow of Lagrangian spherical surfaces in complex Euclidean plane

Abstract

We describe the evolution under the mean curvature flow of embedded Lagrangian spherical surfaces in the complex Euclidean plane C2. In particular, we answer the Question 4.7 addressed in [10] by A. Neves about finding out a condition on a starting Lagrangian torus in C2 such that the corresponding mean curvature flow becomes extinct at finite time and converges after rescaling to the Clifford torus.
