Formal Topology in Univalent Foundations
, 2020 Formal topology is a mathematical discipline that aims to interpret topology in type-theoretical terms, that is, constructively and predicatively. Type theory has recently undergone a transformation [42] through insights arising from its association ...

Coefficient Regions for Univalent Trinomials
, 1980 The problem of determining necessary and sufficient conditions bearing upon the numbers a2 and a3 in order that the polynomial z + a2z2 + a3z3 be univalent in the unit disk |z| < 1 was solved by Brannan ([3], [4]) and by Cowling and Royster [6], at ...

Coefficients Of The Inverse Of Strongly Starlike Functions. [PDF]
, 2003 For the class of strongly starlike functions, sharp bounds on the first four coefficients of the inverse functions are determined. A sharp estimate for the Fekete-Szego coefficient functional is also obtained.

Integral representations of univalent functions and singular measures
, 1990 In [5], T. MacGregor showed that not every univalent function has a proposed integral representation with respect to Borel measures on the unit circle. In this paper, we study the decomposition of measures which do give rise to univalent functions.

Subclass of harmonic starlike functions associated with salagean derivative
Le Matematiche, 2014 The purpose of the present paper is to establish some results involving coefficient conditions, distortion bounds, extreme points, convolution, and convex combinations for a new class of harmonic univalent functions in the open unit disc \ associated ...

Inverse and Logarithmic Coefficient Bounds of Concave Univalent Functions
AxiomsThe concept of coefficient estimates on univalent functions is one of the interesting aspects explored recently by many researchers. Motivated by this direction, in this present work, we obtain the upper bounds of initial inverse coefficients and ...

On the univalency of Cesàro sums of univalent functions [PDF]
Bulletin of the American Mathematical Society, 1936 openaire +2 more sources
, 1962 A function f(z) is said to be univalent in a region G if and only if f(z1) = f(s2 ) in G implies z1 = z2 whenever z1 and z2 are any two points in G. Another way of stating this is that a univalent function in G is characterized by the fact that it takes ...

Demonstratio MathematicaA 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 ...

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
