SANDWICH THEOREMS FOR GENERALIZED INTEGRAL OPERATOR

Abstract

We introduce some applications of first order differential subordination and superordination to obtain sufficient conditions for generalized integral operator to satisfy q1(z) ≺ z[Lq,s δ (α1 , α2 , … , αq; β1 , β2 , … , βs )f(z)] ′ Φ[Lq,s δ (α1 , α2 , … , αq; β1 , β2 , … , βs )f(z)] ≺ q2(z) Mathematics Subject Classification: 30C80, 30C45
