Query: Existence of positive solutions of a Hammerstein integral equation using
  the layered compression-expansion fixed point theorem   In this paper, we show the existence of a positive solution of a Hammerstein
integral equation under certain conditions on the kernel. We apply the recent
Layered Compression-Expansion Fixed Point Theorem. Finally, we provide
corollaries to help in application of the main results and present an example.
