Oscillation and nonoscillation theorems for a class of even-order quasilinear functional differential equations (Q2471855)

This paper is concerned with the oscillatory and nonoscillatory behaviour of solutions of even-order quasilinear functional differential equations of the form \[ (| y^{(n)}(t)| ^{}\text{sgn\,} y^{(n)}(t))^{(n)}+q(t)| y(g(t))| ^{}\text{sgn\,} y(g(t))=0. \] An example illustrating the results is presented.
