Nonnegative radial solutions to a class of elliptic equations involving the Pucci's extremal operator

In this article we use Leray–Schauder degree to consider the existence of nonnegative radially symmetric solution for the nonlinear elliptic equation in BR, y=0 on ∂BR, where denotes the Pucci's extremal operators with parameters 0<λ⩽Λ and BR is the ball of radius R in RN, N⩾3. As an application we can obtain the results to equation , where and 0
