A Floquet-Lyapunov Theory for nonautonomous linear periodic differential equations with piecewise constant deviating arguments
Ricardo Torres
We present a version of the classical Floquet-Lyapunov theorem for periodic nonautonomous linear (impulsive and non-impulsive) differential equations with piecewise constant ar…

On oscillations of nonautonomous linear impulsive differential equations with general piecewise constant deviating arguments
Ricardo Torres
We give some sufficient conditions that ensure oscillations and nonoscillations for nonautonomous impulsive differential equations with piecewise constant arguments of generalized…

A variation of parameters formula for nonautonomous linear impulsive differential equations with piecewise constant arguments of generalized type
Ricardo Torres, Manuel Pinto
In this work, we give a variation of parameters formula for nonautonomous linear impulsive differential equations with piecewise constant arguments of generalized type. We cover se…
