Abstract:
In this article we study the existence and multiplicity of positive
solutions for the system of second-order boundary value problems
involving first order derivatives
Here
.
We use fixed point index theory to establish our main results based
on a priori estimates achieved by utilizing Jensen's integral
inequality for concave functions and
-monotone matrices.
