Greenʹs function for second order differential equations with piecewise constant arguments Original Research Article

In this paper, the second order nonautonomous differential equations with piecewise constant arguments View the MathML sourcex″(t)+(α(t)-β(t))x′(t)-(β′(t)+α(t)β(t))x(t)+c(t)x′([t])+d(t)x([t])=σ(t),t∈[0,T],x(0)=x(T),x′(0)=x′(T)+λ Turn MathJax on is considered. We obtain the Greenʹs function to express the unique solution for the system.
