Univalent functions with negative coefficients

, 1975
Coefficient, distortion, covering, and coefficient inequalities are determined for univalent functions with negative coefficients that are starlike of order α \alpha and convex of order α \alpha .

Robot‐Assisted Measurement of the Critical Micelle Concentration

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The study introduces (SIMO) smart integrator for manual operations, a robotic platform for precise, repeatable determination of (CMC) critical micelle concentration in surfactants. SIMO reduces standard deviation by 80% compared to manual methods. Surfactant, dye, and diluent selection, robotic protocols, and data handling are detailed.

Harmonic univalent functions [PDF]

, 2009
Harmonik fonksiyonlar analitik olması gerekmeyen kompleks değerli fonksiyonlardır. Harmonik yalınkat fonksiyonlar teorisi ise kompleks analizin üzerinde en çok araştırma yapılan dallarından birisidir.

Generalized Salagean-type harmonic univalent functions

, 2012
The main purpose of this paper is to introduce a generalization of modified Salagean operator for harmonic univalent functions. We define a new subclass of complex-valued harmonic univalent functions by using this operator, and we investigate necessary ...

Goodman’s conjecture and the coefficients of univalent functions

, 1978
Goodman’s conjecture (for a bound on the modulus of the nth coefficient of a p-valent function as a linear combination of the moduli of the first p coefficients) is considered in the special case of functions which are polynomials of univalent functions.

An equation for complex fractional diffusion created by the Struve function with a T-symmetric univalent solution

Demonstratio Mathematica
A TT-symmetric univalent function is a complex valued function that is conformally mapping the unit disk onto itself and satisfies the symmetry condition ϕ[T](ζ)=[ϕ(ζT)]1∕T{\phi }^{\left[T]}\left(\zeta )={\left[\phi \left({\zeta }^{T})]}^{1/T} for all ζ ...
