Abstract. This paper presents several su cient conditions for the existenceof at least one weak solution for the impulsive nonlinear fractional boundaryvalue problem . Our technical approach is based on variational methods. Somerecent results are extended and improved. Moreover, a concrete example of anapplication is presented.
