| Abstract: | In this paper, we investigate the step operators for the quasi-exactly solvable problems. We also discuss the commutation relations between the step operators and the Hamiltonian of the quasi-exactly solvable system. After obtaining the general results, we take the anharmonic oscillators with x 6 anharmonicity in quasi-exactly solvable problems as examples to give the specific forms of step operators. |
