Abstract: Conditions for the existence of nontrivial bounded solutions of the stationary Schrodinger equation with a finite energy integral on model varieties are obtained. A condition for the existence of nontrivial bounded solutions with a finite integral of energy in the exterior of a compactum on arbitrary Riemannian manifolds is also obtained. Let $D=(0;+\infty)\times S,$ where $S$ is compact Riemannian manifold. Metrics on $D$ is following
$$ds^2=dr^2+g^2(r)d\theta^2.$$
Where $g(r)$ is positive, smooth on $(0,+\infty)$ function, $d\theta^2$ is metrics on $S.$ We will study solutions of the stationary Schrodinger equation
$$\Delta u-c(r)u=0$$
on $D$. Let $r_0=\mathrm{const} >0, n=\dim D$.
Theorem 1. Theorem 2. On an arbitrary Riemannian manifold $ M $, the convergence of the energy integral of the Liouville function of the exterior of the compact (Liouville function of the end) implies the convergence of the energy integral of the Liouville function.

Keywords: energy integral, stationary Schrödinger equation, Liouville function, massive sets, Riemannian manifolds.
