In this research, a necessary and sufficient condition is given for a superposition operator to act from the sequence space Fr(p) to the space Moreover, a necessary and sufficient condition is obtained for a superposition operator acting from Fr(p) to to be locally bounded, bounded, and continuous respectively.
