 note = {In this paper, initial value problems of fractional differential equations are discussed. We obtain the existence and uniqueness of solutions for the problems. Two proofs are given. In the _rst proof, we don't use any _xed point theorems. In the second proof, we use the _xed point theorem for contraction mappings.},
