摘要
本文研究了无穷维Hamilton算子的可逆性问题,进而,刻画了无穷维Hamilton算子的谱的分布,并运用内部的逆紧性描述了无穷维Hamilton算子的逆紧性.最后,给出了无穷维Hamilton算子的可逆性问题在Dirac算子的可逆性问题中的应用.
In this paper the invertibility of infinite-dimensional Hamiltonian operators which arise in infinitedimensional Hamiltonian systems are studied. The results allow to illustrate the spectral properties of infinite dimensional Hamiltonian operators and characterize the compactness of inverse by applying its entries. In the end, applications to the invertibility of Dirac operators are given.
