About One of Schauder's Theorems

abstract:
The parameter continuation method plays an important role in the theory of linear operators and linear boundary value problems. This method is based on Schauder's theorem on the invertibility of the sum of two linear operators, the first of which is invertible and the sum satisfies a certain condition. In the present paper, the mentioned assertion is extended for arbitrary steady properties of linear operators. The corresponding information related to steady properties and examples of steady properties are given. An example of applying the obtained assertions is presented.
