On the Determinants for a Class of Analytic Function Using Sigmoid Beta-Catas Operator [PDF]
Journal of Function SpacesGeometric function theory (GFT) is the study of geometric properties of analytic functions. The cornerstone of GFT is the theory of univalent functions.

Radius Constants of Sigmoid Starlike Functions [PDF]
, 2022 In the present investigation, we study the class of Sigmoid starlike functions, given by $\mathcal{S}^*_{SG}=\{f\in\mathcal{A}: {zf'(z)}/{f(z)}\prec 2/(1+e^{-z})\}$ in context of estimating the sharp radius constants associated with several known subclasses of starlike functions.

Equivalent Analytical Functions of Sums of Sigmoid like Transcendental Functions [PDF]
Applied Mathematics and Nonlinear Sciences, 2018 Abstract There is no mathematical solution to adding up transcendental functions other than numerical process. This paper put forward analytical method to model the sum of sigmoid like functions with an equivalent function. The Brillouin and Langevin as well as the error function, the tanh, sigmoid and the tan-

Coefficient estimates for starlike and convex functions related to sigmoid functions
Ukrains’kyi Matematychnyi Zhurnal, 2023 UDC 517.5 We give sharp coefficient bounds for starlike and convex functions related to modified sigmoid functions. We also provide some sharp coefficients bounds for the inverse functions and sharp bounds for the initial logarithmic coefficients and some coefficient differences.

A Flexible Sigmoid Function of Determinate Growth [PDF]
Annals of Botany, 2002 A new empirical equation for the sigmoid pattern of determinate growth, 'the beta growth function', is presented. It calculates weight (w) in dependence of time, using the following three parameters: t(m), the time at which the maximum growth rate is obtained; t(e), the time at the end of growth; and w(max), the maximal value for w, which is achieved ...
