Article Existence of Positive Solutions to Multi-Point Third Order Problems With Sign Changing Nonlinearities(Univ Tartu Press, 2020) Dogan, Abdulkadir; Graef, John R.In this paper, the authors examine the existence of positive solutions to a third-order boundary value problem having a sign changing nonlinearity. The proof makes use of fixed point index theory. An example is included to illustrate the applicability of the results.
