Sandwich-type theorems for a class of integral operators with special properties
In the present paper, we prove subordination, superordination and sandwich-type properties of a certain integral operators for univalent functions on open unit disc, moreover the special behavior of this class is investigated.

متن کاملTwo Sandwich Theorems for Linear Operators and the Moment Problem
We give a direct proof for theorem 2 [13] (which is equivalent to theorem 1 [15]). Then we apply theorems 1 [15] and 4 [15] to some concrete spaces of sequences or functions which have a Schauder basis. The polynomials xj(t) = t j , j ∈ N considered in the classical moment problem, are replaced by the elements of the Schauder basis. Mathematics Subject Classification: 46A22, 47A57.
متن کاملOn Sandwich theorems for certain classes of analytic functions
The purpose of this present paper is to derive some subordination and superordination results for certain analytic functions in the open unit disk. Relevant connections of the results, which are presented in the paper, with various known results are also considered.
متن کاملDirect Approximation Theorems for Discrete Type Operators
In the present paper we prove direct approximation theorems for discrete type operators (Lnf)(x) = ∞ ∑ k=0 un,k(x)λn,k(f), f ∈ C[0,∞), x ∈ [0,∞) using a modified K−functional. As applications we give direct theorems for Baskakov type operators, Szász-Mirakjan type operators and Lupaş operator.
