Yang, Dianwu A variational principle for three-point boundary value problems with impulse. (English) Zbl 1474.34209 Abstr. Appl. Anal. 2014, Article ID 840408, 6 p. (2014). Summary: We construct a variational functional of a class of three-point boundary value problems with impulse. Using the critical points theory, we study the existence of solutions to second-order three-point boundary value problems with impulse.
