Necessary and sufficient conditions for nonoscillatory solutions of impulsive delay differential equations
Monotonicity of solutions is an important property in the investigation of oscillatory behaviors of differential equations. A number of papers provide some existence criteria for eventually positive increasing solutions. However, relatively little attention is paid to eventually positive solutions t...
