Abstract

Existence of positive radially symmetric solutions to a Dirichlet problem of the form -div(A(|Du|)Du) = ƒ(u) in Ω u = 0 on ∂Ω is studied by using blow-up techniques. It is proven here that by choosing the functions sA(s) and f(s) among a certain class called asymptotically homogeneous, the blow-up method still provides the a-priori bounds for positive solutions. Existence is proved then by using degree theory.
