Authors: ERBİL ÇETİN, FATMA SERAP TOPAL

Abstract: This work is concerned with the existence of positive solutions to a nonlinear nonlocal first-order multipoint problem. Here the nonlinearity is allowed to take on negative values, not only positive values.

Keywords: Positive solution, nonlinear boundary condition, sign-changing problem
