Differential Sandwich Theorems for Atangana–Baleanu Fractional Integral Applied to Extended Multiplier Transformation

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
In this paper we derive subordination and superordination results regarding the Atangana–Baleanu fractional integral applied to multiplier transformation and we give several differential sandwich‐type theorems. Then, we apply the Atangana–Baleanu fractional integral to extended multiplier transformation on the class Aζ∗ of normalized analytic functions

Fuzzy Best Dominants for Certain Fuzzy Differential Subordinations

Journal of Advances in Applied & Computational Mathematics, 2022
This paper aims to present a survey on certain fuzzy subordination properties for analytic functions defined in the open unit disk. The new results are derived by considering a certain differential operator. By making use of two differential properties of the operator we determine sufficient conditions to find the fuzzy best dominants for several fuzzy

Certain Integral Operator Related to the Hurwitz–Lerch Zeta Function

Journal of Complex Analysis, Volume 2018, Issue 1, 2018., 2018
The aim of the present paper is to investigate several third‐order differential subordinations, differential superordination properties, and sandwich‐type theorems of an integral operator Ws,bf(z) involving the Hurwitz–Lerch Zeta function. We make some applications of the operator Ws,bf(z) for meromorphic functions.

Are subordinate ants the best seed dispersers? Linking dominance hierarchies and seed dispersal ability in myrmecochory interactions

Arthropod-Plant Interactions, 2011
True myrmecochory involves the dispersal of elaiosome-bearing seeds by ants. Between the guild of ants that are attracted to these seeds, only a few of them will act as effective dispersers, that is, transporting the seeds to suitable sites (the nests) for germination and plant estab- lishment. Ant communities are known to be highly hier- archical, and
