/section{Introduction}
We shall establish criteria so that system /cite{arnold} has at
least three fixed-sign solutions. In addition, estimates on the
norms of these solutions will also be provided.
The present work is motivated by the fact that boundary value
problems model numerous physical phenomena in nature, hence it is
of fundamental importance to know the criteria that ensure the
existence of at least one meaningful solution.$p_{n - 1}^{/lambda
_i } ,p_{n - 2}^{/lambda _i } ,...,p_1^{/lambda _i } $
/[p_{n - 1}^{/lambda _i } ,p_{n - 2}^{/lambda _i }
,...,p_1^{/lambda _i } /]
/columnseprule=1pt
/begin{multicols}{2}
The paper is organized as follows. Section 2 contains
the necessary definitions and fixed point theorems. The existence
criteria are developed and discussed in Section 3. Finally,
examples are presented in Section 4 to illustrate the importance
of the results obtained.
