On Some Sandwich Results of Univalent Functions Related by Differential Operator

“…Using the results (see [11,[18][19][20][21][22][23][24][25][26][27][28][29][30][31]) t𝑜 o𝑏𝑡ain suffici𝑒nt co𝑛𝑑itions for normalized an𝑎lytic functi𝑜ns to s𝑎𝑡isfy:…”

Recently, several researchers obtained sandwich theorems for subclasses of analytic functions (see [3,[5][6][7][8]10,[12][13][14]18,20,[26][27][28][29][30][31]) .

On Third-Order Differential Subordination and Superordination Properties of Analytic Functions Defined by a Generalized Operator

“…Recently, several authors studied some applications on the concept of second-order differential subordination and superordination and established some sandwich outcomes, like, (see [12,13]) and third-order for different classes (see [8,9,14]). For some interesting applications related to the differential subordination and superordination in other subjects of mathematics, we may refer to [15][16][17].…”

Revised Manuscript On New Sandwich Results of Univalent Functions Defined by a Linear Operator

“…Recently, several authors [2,[23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] gave sandwich-type sequences for types of analytic functions using another sufficient conditions . 2.…”
