# Generalization of the Kneser theorem on zeros of solutions of the equation $y" + p (t) y = 0$

Slyusarchuk V. Yu.

Abstract

We obtain conditions of the oscillation of solutions of the equation $y" + p(t)Ay = 0$ in the Banach space, where $A$ is a bounded linear operator and $p : R_+ \rightarrow R_+$ is a continuous function.
