Abstract in Portuguese
Estudamos uma classe de sistemas elípticos - 'elipson POT 2' 'DELTA' u + u = g(v) em 'ÔMEGA' - 'elipson POT 2' 'DELTA' v + v f(u) em ÔMEGA ' PARTIAL'u SOBRE 'PARTIAL n = 'PARTIAL v SOBRE PARTIAL n = O sobre "PARTIAL'' ÔMEGA' onde ' ÔMEGA ESTA CONTIDO EM R POT. N' é um domínio limitado, com bordo regular e N ' > ou =' 3. As não linearidades f e g são funções com crescimento superlinear e subcrítico no infinito. Estudamos resultados sobre a existência de uma sequência de soluções que se concentram, quando o parâmetro 'epsilon' tende a zero, em um ponto da fronteira que maximiza a sua curvatura. Para isso utilizamos um resultado abstrato sobre existência de pontos críticos para funcionais fortemente indefinidos

Abstract in English
We study an singularly perturbed Hamiltonean elliptic system - 'elipson POT 2' 'DELTA' u + u = g(v) in 'ÔMEGA' - 'elipson POT 2' 'DELTA' v + v f(u) in ÔMEGA ' PARTIAL'u ON 'PARTIAL n = 'PARTIAL v ON PARTIAL n' = O sobre "PARTIAL'' ÔMEGA' when 'ÔMEGA THIS CONTAINED R POT. N' is a smooth bounded domain, N ' > or =' 3 and f and g are nonlinearities having superlinear and subcritical growth at infinity. We study an abstract result about existence of critical points of strongly as ' epsilon' goes to zero, at a point of the boundary which maximizes the mean curvature of the boundary
