Solvability conditions and monotone iterative scheme for boundary-value problems related to nonlinear monotone potential operators

摘要

This article deals with boundary-value problems (BVPs) for the second-order nonlinear differential equations with monotone potential operators of type Au := -{nabla}(k(|{nabla}u|~2){nabla}u(x))+q(u~2)u(x), x∈Ω{is contained in}R~n. An analysis of nonlinear problems shows that the potential of the operator A as well as the potential of related BVP plays an important role not only for solvability of these problems and linearization of the nonlinear operator, but also for the strong convergence of solutions of corresponding linearized problems. A monotone iterative scheme for the considered BVP is proposed.
