Query: Solvability in Gevrey classes of some nonlinear fractional functional
  differential equations   Our purpose in this paper is to prove, under some regularity conditions on
the datas, the solvability in a Gevrey class of bound -1 on the interval [-1,1]
of a class of nonlinear fractional functional differential equations.
