Journal of Function Spaces, 2023 In this paper, we consider a new general integral operator, defined as a joint extension of two already known integral operators, and prove some univalence properties for this operator. Some other well-known operators are mentioned as particular cases of

Bicategories in univalent foundations [PDF]
Mathematical Structures in Computer Science, 2021 AbstractWe develop bicategory theory in univalent foundations. Guided by the notion of univalence for (1-)categories studied by Ahrens, Kapulkin, and Shulman, we define and study univalent bicategories. To construct examples of univalent bicategories in a modular fashion, we develop displayed bicategories, an analog of displayed 1-categories introduced

Univalency of Certain Transform of Univalent Functions
Proceedings of the Bulgarian Academy of Sciences, 2023 We consider univalency problem in the unit disc $$\mathbb{D}$$ of the function \[g(z)=\frac{(z/f(z))-1}{-a_{2}}, \] where $$f$$ belongs to some classes of univalent functions in $$\mathbb{D}$$ and $$a_{2}=\frac{f''(0)}{2}\neq 0$$.

Univalence Criteria for Locally Univalent Analytic Functions
Ukrainian Mathematical Journal, 2023 UDC 517.5 Suppose that p ( z ) = 1 + z ϕ ' ' ( z ) / ϕ ' ( z ) , where ϕ ( z ) is a locally univalent analytic function in the unit disk D with ϕ ( 0 ) = ϕ ' ( 1 ) - 1 = 0. We establish the lower and upper bounds for the best constants σ 0

Responses to ambivalence toward social networking sites: A typological perspective
Information Systems Journal, Volume 33, Issue 2, Page 385-416, March 2023., 2023 Abstract A common assumption in prior research on social networking sites (SNS) has been that users' orientations toward SNS use are positioned somewhere along a bipolar, univalent continuum, stretching from negative to positive orientation. However, considering recent findings unfolding the intricacy and variety of SNS use patterns, such a linear ...

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

Perovskite semiconductors for ionizing radiation detection
EcoMat, 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 ...

Towards a constructive simplicial model of Univalent Foundations
Journal of the London Mathematical Society, Volume 105, Issue 2, Page 1073-1109, March 2022., 2022 Abstract We provide a partial solution to the problem of defining a constructive version of Voevodsky's simplicial model of Univalent Foundations. For this, we prove constructive counterparts of the necessary results of simplicial homotopy theory, building on the constructive version of the Kan‐Quillen model structure established by the second‐named ...

The Univalence of an Integral [PDF]
Proceedings of the American Mathematical Society, 1971 Let f ( z ) f(z) be a normalized function, analytic and univalent in the open unit disc. It is shown that if g ( z ) = ∫ 0 z ( f ( t
