Representation of solutions of general linear differential systems of the second order
Methods of oscillation theory of half-linear second order differential equations
In this paper we investigate oscillatory properties of the second order half-linear equation Using the Riccati technique, the variational method and the reciprocity principle we establish new oscillation and nonoscillation criteria for (*). We also offer alternative methods of proofs of some recent oscillation results.
