摘要:

该文研究了无穷维Hamilton算子的特征函数系, 给出了特征函数系在一般意义下不能完备的无穷维Hamilton算子的类. 进而, 解决了对一类无穷维Hamilton算子所对应的Hamilton系统能否可以应用传统分离变量法的问题. 最后, 举出了具体的例子, 加以说明判别准则的有效性.

Abstract:

In this paper, we study the eigenfunction systems of infinite dimensional Hamiltonian operator and obtain a class of infinite dimensional Hamiltonian operators whose eigenfunction systems are not complete in Hilbert space X×X, which is helpful to solve the problems that the method of separation of variable whether can be used in a class of Hamiltonian systems. In the end, concrete examples are constructed to justify the effectiveness of the criterion.

Key words: Infinite dimensional Hamiltonian operator, k-compact operator, Eigenfunction system, Cauchy principal value, Completeness
