We review the recent generalized fractional calculus of variations. We
consider variational problems containing generalized fractional integrals and
derivatives and study them using indirect methods. In particular, we provide
necessary optimality conditions of Euler-Lagrange type for the fundamental and
isoperimetric problems, natural boundary conditions, and Noether type theorems.Comment: This is a preprint of a paper whose final and definite form will
appear in Southeast Asian Bulletin of Mathematics (2014
