Abstract

In this paper, we generalize Medos–Wang’s arguments and results on the mean curvature ow deformations of symplectomorphisms of $\mathbb{C}P^n$ in [MeWa] to complex Grassmann manifold $G(n, n + m; \mathbb{C})$ and compact totally geodesic Kähler–Einstein submanifolds of it. We also give an abstract result and discuss the case of complex tori.
