We study the existence of positive solutions to the three

\r\npoints difference-summation boundary value problem. We show the

\r\nexistence of at least one positive solution if f is either superlinear or

\r\nsublinear by applying the fixed point theorem due to Krasnoselskii

\r\nin cones.<\/p>\r\n",
