Existence of solutions to nonlinear problems with three-point boundary conditions
Using Leray-Schauder degree theory and the method of upper and lower solutions, we obtain a solution for nonlinear boundary-value problem $$\displaylines{ \big(\varphi(u' )\big)'= f(t,u,u') \cr l(u,u')=0, }$$ where l(u,u')=0 denotes the three-point boundary conditio...
