摘要：
In this paper, by using the eigenvalue theory, the sub-sup ersolution method and the fixed point theory, we prove the existence, multiplicity, unique-ness, asymptotic behavior and approximation of positive solutions for singu-lar multiparameter p-Laplacian elliptic systems on nonlinearities with separate variables or without separate variables. Various nonexistence results of positive solutions are also studied.
