摘要
We study through the lower and upper-solution method, the existence of positive weak solution to the quasilinear elliptic system with weights [GRAPHICS] where Omega is a bounded smooth domain of R-N, with 0 is an element of Omega, 1 < p, q < N, 0 <= a < N-p/p, 0 <= b < N-q/q, 0 <= alpha < p - 1, 0 <= beta < q - 1, delta, gamma, c(1), c(2) > 0 and 0 := (p - 1 - alpha)(q - 1 - beta) -gamma delta > 0, for each lambda > 0.
