Positive radial solutions for a quasilinear system.

In this article, general existence theorems are presented for a quasilinear system We obtain some existence theorems by a simple application of the Schauder fixed-point theorem and degree theory. We do not require conditions of the nonlinearity f ,   g at zero or at infinity, and we do not need upper bounds for p ,   q involving the dimension n . We study the case where problem ( P ) is not of variational type. [ABSTRACT FROM AUTHOR]
