摘要
本文应用非负Hamilton算子的特殊结构,证明了一类非负Hamilton算子的点谱分布,并且证明了虚轴包含在此类非负Hamilton算子的连续谱和预解集中.由此给出可逆的充要条件.
In this paper,applying the special structure of nonnegative Hamiltonian operators, the distribution of point spectrum of a class of nonnegative Hamiltonian operators is obtained.It is proved that imaginary axis is a subset of its continuous spectrum and resolvent set, by the above result, necessary and sufficient condition of invertibility for a class of nonnegative Hamiltonian operators is obtained.
