【 摘 要 】

We consider the following boundary value problem: [GRAPHICS] where 1 less than or equal to p less than or equal to n - 1 is fixed. Using a fixed point theorem for operators on a cone, we develop criteria for the existence of two positive solutions of the boundary value problem. In addition, upper and lower bounds for these positive solutions are established for special cases. We also include several examples to dwell upon the importance of the results obtained.
