| Abstract: | In this article, the author employs the conical expansion and compression fixed point principle and the fixed point index theory to show that there exist at least two positive solutions for a higher order BVP. |
| Keywords: | Multiple positive solutions higher order BVP nonlinear differential equation fixed point index Banach space |
