On Positive Singular Solutions for a Class of Nonhomogeneousp-Laplacian-Like Equations

We study the behavior of positive radial solutions to−div(A( u) u)=f(u)near an isolated singularity atx=0. We give an a priori estimate of the order of such singularity without imposing any growth restriction onAorf, and classify the solutions under an asymptotic Serrin type condition for strongly nonhomogeneous (possibly unbounded) functionsA. We also prove the existence of such solutions.
