A q-Rogers–Ramanujan-based characterization of q-bi-bounded turning functions

Demonstratio Mathematica
This study investigates the second Hankel determinant for a specific class of functions associated with the q-Rogers–Ramanujan polynomial. To accomplish this, we introduce a new subclass of q-bounded turning functions related to the q-Rogers–Ramanujan ...

New Criteria for Functions in a Class of Meromorphically Strongly Starlike Functions

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
The authors propose to investigate some new criteria for a certain class of meromorphically strongly starlike functions in the punctured open unit disk. Some intriguing applications that arise as special cases of the main results, which are presented in ...

The order of starlikeness of some classes of strongly starlike functions

, 2018
In this paper we consider the order of strongly starlikeness for functions in Silverman's class Gb and in the generalized Mocanu's class M (α, β1, β2). Some previous results are improved.Mathematics Subject Classification (2010): Primary 30C45; Secondary
