Univalent functions with logarithmic restrictions [PDF]
, 1991 It is known that univalence property of regular functions is better understood in terms of some restrictions of logarithmic type. Such restrictions are connected with natural stratifications of the studied classes of univalent functions.

Asymptotic Conformality and Polygonal Approximation
AxiomsUnivalent functions with asymptotically conformal extension to the boundary form a subclass of functions with quasiconformal extension with rather special features.

Coefficient problem for certain subclasses of bi-univalent functions defined by convolution [PDF]
Mathematica Moravica, 2016 In this paper, we consider a general subclass HλΣ (h, β) of bi-univalent functions. Bounds on the first two coefficients اa2ا and اa3ا for functions in HλΣ (h, β) are given. The main results generalize and improve a recent one obtained by Srivastava [18].

Initial Coefficients of Biunivalent Functions
Abstract and Applied Analysis, 2014 An analytic function f defined on the open unit disk is biunivalent if the function f and its inverse f-1 are univalent in 𝔻. Estimates for the initial coefficients of biunivalent functions f are investigated when f and f-1, respectively, belong to some ...

Advanced Science, EarlyView.Heteroatom precursor engineering serves as a molecular‐level strategy to tailor hydrazide monomer reactivity and diffusion kinetics, enabling controlled assembly of highly crystalline COF membranes with ultramicroporous channels. The nitrogen‐enriched nanochannels deliver high water/ion selectivity via simultaneous water transport acceleration and ion ...

Univalent functions and the Riemann mapping theorem
, 1976 A proof of the Riemann mapping theorem is given that depends on variational formulas for univalent functions. The method of proof can be used to simplify the derivation of the ordinary differential equation for extremal univalent functions given by ...

On the subclass of regular univalent functions
, 1987 In this thesis, we prove the results due to R.J. Libera and A. E. Livingston concerning the subclasses of regular, univalent functions such as class of starlike functions, class of convex functions and class of close-to-convex functions. Further, we show

Some Properties of a Subclass Involving Close - to - Convex of Univalent and Multivalent Functions
Wasit Journal for Pure SciencesOur work included studying some subclasses of functions (univalent - multivalent) that are close to convex. which is divide into two parts. First part, we discussed the properties of parameter estimates, the implication relation, distortion theorem, and
