Abstract
In the present paper, we introduce a family of integral operators Ip,n,δλ,μ(a,b,c) associate with the Noor integral operator in the open unit disk U={z∈C:|z|<1}U={z∈C:|z|<1}, which is defined by the convolution [fp,δμ(a,b,c)(z)](-1)*f(z), wherefp,δμ(a,b,c)(z)=(1-μ+δ)zp2F1(a,b;c;z)+(μ-δ)z[zp2F1(a,b;c;z)]′+μδz2[zp2F1(a,b;c;z)]″(p∈N={1,2,⋯};μ,δ⩾0;z∈U).By using the operator Ip,n,δλ,μ(a,b,c), we investigate some subordination and superordination preserving properties for certain classes of analytic and multivalent functions in UU. Various sandwich-type results for these multivalent functions are also obtained.
