Abstract:

 This present paper defines and researches the ρ(r) relative deficiency of a meromorphic function and obtains four results. Theorem 2 contains Sarangi and Patils result's. Theorem 4 states clearly that meromorphic functions with maximal ρ(r) deficiency sum haven't non zero and finite ρ(r) relative deficient values.
