Annotation
The spectral properties of the Schrodinger operator of two-dimensional two-electron atomic systems are investigated. Tirring estimates are obtained for the ground-state energy. Within the framework of the variational method and the Hylleraas method, the ground-state energy is calculated in the first and third approximations.
