In this talk, we analyze nonlinear differential equations subject to generalized boundary conditions. More specifically, I will provide a framework from which we can provide conditions, which are straightforward to check, for the solvability of a large number of nonlinear scalar boundary value problems. I will begin by giving the general strategy which involves a reformulation of our boundary value problem as an operator equation. We then proceed to establish our results and compare them to closely related previous work. This is joint work with Dr. Jesús Rodríguez.
