| Abstract: | The problems are studied that whether the continuous spectrum of an infinite dimensional Hamiltonian operator is empty or not and when it is empty. A necessary and sufficient condition is obtained that the continuous spectrum of upper-triangular-type infinite dimensional Hamiltonian operators is empty and its criterions are given.In the end, a concrete example of infinite dimensional Hamiltonian operators is constructed to justify the effectiveness of the criterions. |
