problem for the relativistic finite-difference Schrцdinger equation with the singular oscillator quasipotential is studied. For this problem eigenvalues and eigenfunctions are considered. It is shown that they have correct non-relativistic limits.

Для собственных функций и собственных значений этой задачи получены соответствующие нерелятивистские пределы.
