Some remarks on three-point and four-point BVP's for second-order nonlinear differential equations
We are interested in the existence of a positive solution to the four-point boundary value problem $$\begin{cases} y''(t)+a(t)f(y(t)) = 0, \quad 0<t<1, y(0)=\alpha y(\xi), y(1)=\beta y(\eta), \end{cases} \tag{*} $$ where $ 0<\xi \leq \eta <1 $, $ 0<\alpha <1/(1-\xi) $,...
