We will use Variational and Topological Methods, which includes minimization of energy functional and building connected components of solutions in a sense that we will define. Also we will employ arguments about the theory of regularity for p-Laplacian operator, approach arguments , maximum principles, results about sub and supersolutions and also arguments including monotonic type operators. / Neste trabalho estudamos a estrutura topológica do conjunto de soluções da classe de problemas −Δpu = λ f (u)+μg(u)|∇u|p+Ψ(x) em Ω, u > 0 em Ω, u = 0 sobre ∂Ω, onde Ω⊂IRN é um domínio limitado com fronteira ∂Ω regular, p, λ, μ são constantes com p > 1, λ ≥ 0, μ ∈ IR e f ,g : (0,∞)→IR, Ψ : Ω→IR são funções contínuas. Utilizamos Métodos Variacionais e Topológicos, que incluem minimização de funcionais energia e construção de componentes conexas de soluções em um sentido que definiremos. Empregamos também argumentos sobre a teoria da regularidade para o operador p- Laplaciano, argumentos de aproximação, bem como princípios de máximo, resultados sobre sub e supersoluções e também argumentos com operadores tipo monotônico.
