Impulsive boundary value problems with nonlinear boundary conditions.

*(English)*Zbl 1171.34309The authors present sufficient conditions for the existence of a solution to a second order boundary value problem with impulses. The problem has nonlinear boundary conditions.

The authors assume the existence of lower and upper solutions associated with the problem considered and that the nonlinearity of the differential equation satisfies a Nagumo-Wintner condition relative to that lower and upper solutions. Besides, some monotonicity conditions on the impulsive functions and on the functions which define the nonlinear boundary conditions are imposed.
