摘要
研究了非负Hamilton算子H=■的可逆性以及有界逆的存在性问题,进而给出了非负Hamilton算子H存在有界逆以及虚轴上的点均为H的正则点的充分条件.
The invertibility and the existence problems on bounded inverse of nonnegatively Hamiltonian operator H =（A B C -A^＊）are studied and sufficient conditions for nonnegatively Hamiltonian operator H exists bounded inverse and points in imaginary axis are all regular point of H are given.
