Second Order Necessary Conditions for Endpoints-Constrained Optimal Control Problems on Riemannian manifolds

Li Deng, Xu Zhang

In this paper, we are concerned with optimal control problems evolved on Riemannian manifolds, where the initial and final states satisfy some inequality and equality type constrai…

$L^{2}$ estimates and existence theorems for the $\partial ˉ$ operators in infinite dimensions, I

Jiayang Yu, Xu Zhang

The classical $L^{2}$ estimate for the $\partial$ operators is a basic tool in complex analysis of several variables. Naturally, it is expected to extend this estimate to…
