In this article we establish a connection between
the confluent Heun equation (with two singularities $0$ and $$¥) and
the Schrödinger equation for the hydrogen atom with two
accessory parameters $$m and $$n, which "influence"
the spectrum of eigenvalues and the Coulomb potential.

All articles are
published in Russian.
