Abstract:
      A new class Mp(n,λ,A,B)(p∈N,n∈N∪{0},-1≤B<A≤1,-π/2<λ<π/2 consisting of meromorphically multivalent functions in the unit disc is introduced.It is proved that Mp(n+1,λ,A,B)?Mp(n,λ,A,B).Integral transforms for functions in the class Mp(n,λ,A,B) are studied.sharp coefficient estimates and a related convolution theorem are also obtained.
