Abstract

We study oscillatory properties of solutions of a functional differential equation of the form

๐‘ข(๐‘›)(๐‘ก) + ๐น(๐‘ข)(๐‘ก) = 0,

where ๐‘› โ‰ฅ 2 and ๐น : ๐ถ(๐‘…+; ๐‘…) โ†’ ๐ฟloc(๐‘…+; ๐‘…) is a continuous mapping. Sufficient conditions for this equation to have the so-called Property A are established. In the case of ordinary differential equation the obtained results lead to an integral generalization of the well-known theorem by Kondrat'ev.
