Several oscillation criteria are established for nonlinear fractional differential equations of the form where is the Liouville right-side fractional derivative of order of and is a quotient of two odd positive integers. We also give some examples to illustrate the main results. To the best of our knowledge, the results are initiation for the oscillatory behavior of the equations.
