Radial solutions for Neumann problems involving mean curvature operators in Euclidean and Minkowski spaces

摘要

In this paper we study the existence of radial solutions for Neumann problems in a ball and in an annular domain, associated to mean curvature operators in Euclidean and Minkowski spaces. Our approach relies on the Leray-Schauder degree together with some fixed point reformulations of our nonlinear Neumann boundary value problems (© 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
