XI.—On q -Functions and a certain Difference Operator
TL;DR: In this paper, the properties of a certain operative symbol which appears to be of great utility in discussing q-functions are investigated, and the first part of the paper will consist of an investigation into the various forms ofand the nature of the inverse operations symbolised by Δ−n.

On a coefficient problem for bi-univalent functions
TL;DR: The bi-univalent function f(z) is defined in this paper as a function that belongs to a set of functions mapping the open unit circle onto a schlicht domain containing open unit circles.

New subclasses of bi-univalent functions
Basem Aref Frasin,M. K. Aouf +1 more
TL;DR: Two new subclasses of the function class Σ of bi-univalent functions defined in the open unit disc are introduced and estimates on the coefficients of functions in these new sub classes are found.
