摘要：
The paper considers operators that map the set E onto itself. If A (phi) = psi, then psi preserves some property of the point phi (here A is an operator and phi, psi epsilon E). Such an approach to operators may serve as a method of solving some problems of mathematics, including the theory of orthogonal series.
