Subordination and superordination of certain linear operator on meromorphic functions [PDF]

, 2016
Using the methods of differential subordination and superordination, sufficient conditions are determined on the differential linear operator of meromorphic functions in the punctured unit disk to obtain, respectively, the best dominant and the best ...

The visual, the textual, and the one‐dimensional: An exploration of the visual elements of bibliographic classification schemes

Journal of the Association for Information Science and Technology, Volume 76, Issue 10, Page 1411-1427, October 2025.
Abstract Classification schemes are a key way of organizing bibliographic knowledge, yet the way that classification schemes communicate their information to classifiers receives little attention. This article takes a novel approach by exploring the visual aspects contained within classification schemes.

Differential Subordination and Superordination for Srivastava‐Attiya Operator [PDF]

International Journal of Differential Equations, 2011
Due to the well‐known Srivastava‐Attiya operator, we investigate here some results relating the p‐valent of the operator with differential subordination and subordination. Further, we obtain some interesting results on sandwich‐type theorem for the same.

Students' Meaning‐Making of Nature of Science: Interaction Between Visual, Verbal, and Written Modes of Representation

Science Education, Volume 109, Issue 2, Page 480-505, March 2025.
ABSTRACT Students' understanding of nature of science (NOS) has been largely examined primarily in written or verbal modes. The visual, verbal, and written modes are essential for students' meaning‐making of NOS. However, research has sidelined the interaction among these three modes in understanding students' collaborative discourse of NOS.

On applications of differential subordination and superordination

Tamkang Journal of Mathematics, 2008
In the present investigation we obtain the sufficient conditions for normalized analytic functions $f$ to satisfy$$ q_1 \prec \frac{f^2}{z^2f'} \prec q_2, $$where $ q_1 $ and $ q_2 $ are univalent functions with $ q_1(0)= q_2(0)=1 $. Also we obtain the sandwich results involving Carlson-Shaffer linear operator, $ S\u{a}l\u{a} $gean derivative and ...

Hankel and Toeplitz Determinants for q‐Starlike Functions Involving a q‐Analog Integral Operator and q‐Exponential Function

Journal of Function Spaces, Volume 2025, Issue 1, 2025.
This article investigates the upper bounds of the second Hankel and Toeplitz determinants for a family of q‐starlike functions defined by a q‐analog integral operator, which is a more general form of the q‐Srivastava‐Attiya operator, and the q‐exponential function eq(z).
