NODAL SOLUTIONS OF NONLOCAL BOUNDARY VALUE PROBLEMS

open access: yesMathematical Modelling and Analysis, 2009
We study the nonlinear boundary value problem consisting of the second order differential equation on [a, b] and a boundary condition involving a Riemann‐Stieltjes integral. By relating it to the eigenvalues of a linear Sturm‐Liouville problem with a two‐point separated boundary condition, we obtain results on the existence and nonexistence of nodal ...
