          |  |  | Abstract: |  We prove the existence of a solution for the nonlinear boundary value problem
 where
 ![$ f:[0,1]times{mathbb{R}}^{m+2}o{mathbb{R}}$](images/021_00_JIPAM/img3.gif) is continuous. The technique used here is a monotone method in the presence of upper and lower solutions. We introduce a new maximum principle which generalizes one due to Bai which in turn was an improvement of a maximum principle by Ma. |
