We use a technique that involves the use of a nonprincipal solution of the associated linear homogeneous equation. The existence of principal and nonpricipal solutions was recently obtained by the present authors. As in special cases, we have superlinear and sublinear Emden-Fowler equations under impulse effects. It is shown that the oscillatory behavior may change due to impulses. An example is also given to illustrate the importance of the results.eninfo:eu-repo/semantics/openAccessimpulsive differential equationnonlinearnonprincipal solutionoscillationsecond-orderArticleQ146549274941WOS:000875669100001
