Detalhes bibliográficos
Resumo:We prove the existence of extremal solutions for the third order discontinuous functional nonlinear problema … by using a fixed point theorem after having established some existence results for some auxiliary second order nonlinear problems. We observe that, together with the discontinuities allowed on the spacial variable u, with adequate modifications of technical type, analogous results can be obtained when the equation has a second member not necessarily continuous in u.
