Existência e simetrias para uma equação elíptica não-linear com potencial monopolar e anisotrópico

Amorim, Charles Braga 27 February 2015 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / This master thesis is concerned to nonlinear elliptic problem with mono-polar anisotropic potential u + u|u|p−1 + v (x)u + f(x) = 0 in Rn u(x) - 0, as |x| - 00 provided n > 3 and p > n n−2 . These results, between others things, deals with sub-critical, critical and super-critical nonlinearity. We obtain well-posedness of solutions, regularity in c2(Rn), symmetries and asymptotic behavior of solutions in singular spaces Hk. We employ Banach fixed technique and a theorem of regularity elliptic to get those results, this technique does not need of the Hardy type inequalities and variational methods. / Nesta dissertação estudamos o problema elíptico u + u|u|p−1 + v (x)u + f(x) = 0 em Rn u(x) - 0, quando |x| - 00 sujeito a restrições n > 3 e p > n n−2 , cobrindo os casos sub-críticos, críticos e super-críticos. Obtemos boa-colocação de soluções, regularidade, simetrias de soluções e comportamento assintótico em espaços singulares Hk. Empregamos um argumento de ponto fixo em Hk e Ek ao invés de usar desigualdades do tipo Hardy e métodos variacionais.
