Generalized Fuzzy Euler-Lagrange equations and transversality conditions
  The study of fuzzy fractional variational problems in terms of a fractional Liouville-Caputo derivative is introduced. Necessary optimality conditions for problems of the fuzzy fractional calculus of variations with free end-points are proved, as well as transversality conditions.
