摘要 | Let (M, (g) over bar) be a Kahler surface, and S an immersed surface in M. The Kahler angle of S inM is introduced by Chern andWolfson [Am. J. Math. 105 (1983) 59-83]. Let (M, (g) over bar (t)) evolve along the Kahler- Ricci flow, and Sigma t in (M, (g) over bar (t)) evolve along the mean- curvature flow. We show that the Kahler angle alpha(t) satisfies the evolution equation (partial derivative/partial derivative(t) - Delta) cos alpha = |(del) over bar J Sigma(t)|(2) cos alpha +Rsin(2) alpha cos alpha, where R is the scalar curvature of (M, (g) over bar (t)). The equation implies that if the initial surface is symplectic (Lagrangian), then, along the flow, St is always symplectic (Lagrangian) at each time t, which we call a symplectic (Lagrangian) Kahler-Ricci mean-curvature flow. In this paper, we mainly study the symplectic Kahler-Ricci mean-curvature flow. |
