    Existence of positive solutions to multi-point third order problems with sign changing nonlinearities
    (UNIV TARTU PRESS, 1 W STRUVE ST, TARTU, 50091, ESTONIA, 2020) Dogan, Abdulkadir; Graef, John R; 0000-0002-7532-1920; 0000-0002-8149-4633; AGÜ, Mühendislik Fakültesi, Bilgisayar Mühendisliği Bölümü
    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.
