Applying the formula, Leighton and Sturm-Picone type comparison theorems as well as several oscillation criteria for impulsive differential equations are obtained.eninfo:eu-repo/semantics/openAccessImpulseLeighton comparisonNon-selfadjointOscillationPicone type formulaSecond orderSturm-Picone comparisonArticleQ2Q31125
