The parabolic quaternionic Monge-Ampère type equation on hyperKähler manifolds

Jixiang Fu, Xin Xu, Dekai Zhang

We prove the long time existence and uniqueness of solution to a parabolic quaternionic Monge-Ampère type equation on a compact hyperKähler manifold. We also show that after normal…

The Monge-Ampère equation for -quaternionic PSH functions on a hyperKähler manifold

Jixiang Fu, Xin Xu, Dekai Zhang

We prove the existence of unique smooth solutions to the quaternionic Monge-Ampère equation for -quaternionic plurisubharmonic functions on a hyperKähler manifold and thus o…

Convexity of Level Sets of Minimal Graph on Space Form with Nonnegative Curvature

Peihe Wang, Dekai Zhang

For the minimal graph defined on a convex ring in the space form with nonnegative curvature, we obtain the regularity and the strict convexity about its level sets by the continuit…
