Horadam Polynomials and a Class of Biunivalent Functions Defined by Ruscheweyh Operator

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2023, Issue 1, 2023., 2023
In this paper, we introduce and investigate a class of biunivalent functions, denoted by Hn,r,α, that depends on the Ruscheweyh operator and defined by means of Horadam polynomials. For functions in this class, we derive the estimations for the initial Taylor–Maclaurin coefficients |a2| and |a3|.

Decomposing the Univalence Axiom [PDF]

open access: yes, 2018
This paper investigates Voevodsky's univalence axiom in intensional Martin-Löf type theory. In particular, it looks at how univalence can be derived from simpler axioms.

Universes and Univalence in Homotopy Type Theory [PDF]

open access: yes, 2019
The Univalence axiom, due to Vladimir Voevodsky, is often taken to be one of the most important discoveries arising from the Homotopy Type Theory (HoTT) research programme.

Perovskite semiconductors for ionizing radiation detection

open access: yesEcoMat, Volume 4, Issue 6, November 2022., 2022
Ionizing radiation detection is a cornerstone technology in multiple application scenarios, such as medical diagnose, safety inspection, and space exploration. Perovskites, as the wonder material of last decade, have been placed with great expectations of widespread applications where semiconductor ionization radiation detection is one preponderant ...

NEIGHBOURHOODS OF UNIVALENT FUNCTIONS [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2010
AbstractThe main result shows that a small perturbation of a univalent function is again a univalent function, hence a univalent function has a neighbourhood consisting entirely of univalent functions. For the particular choice of a linear function in the hypothesis of the main theorem, we obtain a corollary which is equivalent to the classical Noshiro–

A univalency criterion.

open access: yesMichigan Mathematical Journal, 1985
Let f be meromorphic and locally univalent in the upper half plane U with Schwarzian derivative S(f,z). Suppose that \(| 2(Im z)S(f,z)-c(c- 1)| \leq k| c|\) for all \(z\in U\).

UNIVALENCE OF HARMONIC FUNCTIONS, PROBLEM OF PONNUSAMY AND SAIRAM, AND CONSTRUCTIONS OF UNIVALENT POLYNOMIALS

open access: yesПроблемы анализа, 2014
The criteria of the univalence of a harmonic mapping is obtained in this paper. Particularly, it permits to formulate the hypothesis of the harmonic function classes equality S 0 H = S 0 H(S) (hypothesis of Ponnusamy and Sairam), in analytic form.

Global Univalence when Mappings are not Necessarily Continuous

open access: yesReview of Economic Analysis, 2012
This paper proposes a method of establishing the global univalence of a mapping without the assumption of continuity and the absence of points of inflection.
