By making use of subordination between analytic functions and the Dziok-Srivastava operator, we introduce a new subclass of multivalent analytic functions. Such results as inclusion relationship, integral presentations and convolution properties for this function class are proved.

The object of the present paper is to introduce and study a new class of multivalent analytic functions associated with an integral operator Qαβ which was investigated recently by Jung, Kim and Srivastava [J.Math.Anal.Appl. 176(1993), 138-147].

In this paper, we introduce new subclasses k−STs(p,β) and k−UKs(p,β) of analytic univalent functions in the canonical domain associated with Srivastava Attiya operator. The radius problems these regarding symmetrical points are investigated compared previous known results. Certain properties conditions such as integral representation also discussed work.

Suppose that m,n ∈ N and that A : R → R is a linear operator. It is shown here that if k, r ∈ N satisfy k < r 6 rank(A) then there exists a subset σ ⊆ {1, . . . ,m} with |σ| = k such that the restriction of A to R ⊆ R is invertible, and moreover the operator norm of the inverse A−1 : A(R) → R is at most a constant multiple of the quantity √ mr/((r − k) ∑m i=r si(A) 2), where s1(A) > . . . > sm(...

This article presents a new q-analog integral operator, which generalizes the q-Srivastava–Attiya operator. Using this we define family of analytic non-Bazilevi? functions, denoted as Tq,?+1,u?(?,?,M,N). Furthermore, investigate differential subordination properties univalent functions using q-calculus, includes best dominance, subordination, and sandwich-type properties. Our results are proven...
