About sign-constancy of Green’s function of a two-point problem for impulsive second order delay equations
We consider the following second order differential equation with delay $$ \begin{cases} \begin{split} (Lx)(t)&\equiv{x''(t)+\sum_{j=1}^p {a_{j}(t)x'(t-\tau_{j}(t))}+\sum_{j=1}^p {b_{j}(t)x(t-\theta_{j}(t))}}=f(t), & t\in[0,\omega] \end{split} \\ x(t_k)=\gamma_{k}x(t_k-0), \...
