Rezumat:

In this letter we are concerned with the possibility to approach the existence of solutions to
a class of discontinuous dynamical systems of fractional order. In this purpose, the underlying
initial value problem is transformed into a fractional set-valued problem. Next, the Cellina’s
Theorem is applied leading to a single-valued continuous initial value problem of fractional
order. The existence of solutions is assured by a P¶eano like theorem for ordinary di®erential
equations of fractional order.
