%0 Journal Article %T Fractional-Order Variational Calculus with Generalized Boundary Conditions %A Herzallah MohamedAE %A Baleanu Dumitru %J Advances in Difference Equations %D 2011 %I Springer %X This paper presents the necessary and sufficient optimality conditions for fractional variational problems involving the right and the left fractional integrals and fractional derivatives defined in the sense of Riemman-Liouville with a Lagrangian depending on the free end-points. To illustrate our approach, two examples are discussed in detail. %U http://www.advancesindifferenceequations.com/content/2011/357580
