Differential subordinations obtained by using a fractional operator

, 2018
We investigate several differential subordinations using the fractional operator Dν,n : A → A, for −∞ < λ < 2, ν > −1, n ∈ N0 = {0, 1, 2, . . .}, introduced in [7].

Coefficient functionals for Sakaguchi-type-Starlike functions subordinated to the three-leaf function

Demonstratio Mathematica
A challenging part of studying geometric function theory is figuring out the sharp boundaries for coefficient-related problems that crop up in the Taylor-Maclaurin series of univalent functions.

Analytic solutions of a generalized complex multi-dimensional system with fractional order

Demonstratio Mathematica
The Duhamel principle is a mathematical principle that allows us to solve linear partial differential equations. This system is generalized by the concept of the kk-symbol fractional calculus.
