Positive solutions for second-order boundary-value problems with sign changing Green's functions. <i>Electronic Journal of Differential Equations, 2017</i>(245), pp. 1-17.1072-6691https://hdl.handle.net/10877/16037In this article we analyze some possibilities of finding positive solutions for second-order boundary-value problems with the Dirichlet and periodic boundary conditions, for which the corresponding Green's functions change sign. The obtained results can also be adapted to Neumann and mixed boundary conditions.Text17 pages1 file (.pdf)enAttribution 4.0 InternationalSecond order differential equationsDirichlet boundary conditionsPeriodic boundary conditionsSign changing Green's functionArticle
