Motivated by some recent developments for half-linear type elliptic equations, we obtain Picone-type inequalities for two pairs of elliptic type equations with damping and external terms in order to establish Sturmian comparison theorems. Some oscillation results are given as applications.en10.14232/ejqtde.2016.8.23info:eu-repo/semantics/openAccesselliptic equationshalf-linear equationsoscillationPicone's inequalitySturm theoryArticleWOS:000390590900006Q1
