Previous issue date: 2014-03-28 / Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPq / In this work we study existence and multiplicity of non-negative solutions of the nonlinear
elliptic problem −div(A(x,∇u)) = λf(x,u) in Ω, u = 0 in ∂Ω where Ω⊂IRN is a bounded domain with smooth boundary∂Ω,λ≥ 0 is a parameter, f :Ω×[0,∞)−→ IR and A :Ω×IRN−→ IRN satisfy the Carathéodory conditions, A is monotone and f satisfies a growth condition. To this end we use the method of Sub and Supersolutions, Topological Degree Theory, simmetry arguments and variational methods. / Neste trabalho estudaremos existência e multiplicidade de soluções não-negativas do problema elíptico não-linear −div(A(x,∇u)) = λf(x,u) em Ω, u = 0 em ∂Ω, Onde Ω ⊂ IRN é um domínio limitado com fronteira∂Ω suave,λ≥ 0 é um parâmetro, f :Ω×[0,∞)−→ IR e A :Ω×IRN−→ IRN satisfazem as condições de Carathéodory, A é monotônico e f satisfaz uma condição de crescimento. Para este fim utilizaremos o método de Sub e Super Soluções, Teoria do Grau Topológico, argumentos de simetria e métodos variacionais.
