Existence of three positive solutions to a second-order boundary value problem on a measure chain. (English) Zbl 1032.39009
The authors use the so called “five functionals fixed point theorem”, a generalization of the Leggett-Williams fixed point theorem, in order to prove the existence of at least three positive solutions of a boundary value problem. This boundary value problem consists of a second order dynamic equation on a measure chain/time scale and a Sturm-Liouville type boundary condition.
