Abstract

Mathematics Mathematics, Applied Physical Sciences Science & Technology
This paper is concerned with a boundary value problem of the nonlinear q-difference equation - D(q)(2)u(t) = f(t, u(t)), with some boundary conditions. Under certain conditions on f, the existence of positive solutions is obtained by applying a fixed point theorem in cones.
