# Oscillatory criteria for second order differential equations with several sublinear neutral terms

Blanka Baculikova

Abstract. In this paper, sufficient conditions for oscillation of the second order differential equations with several sublinear neutral terms are established. The results obtained generalize and extend those reported in the literature. Several examples are included to illustrate the importance and novelty of the presented results.

Keywords: second order neutral differential equation, sub-linear neutral term, oscillation.

Mathematics Subject Classification: 34K11, 34C10.
