Hankel Determinant of Logarithmic Coefficients for Tilted Starlike Functions With Respect to Conjugate Points [PDF]

open access: yesInternational Journal of Analysis and Applications, 2023
The growth of the Hankel determinant whose elements are logarithmic coefficients for different subclasses of univalent functions has recently attracted considerable interest.

Sharp Bounds for the Second Hankel Determinant of Logarithmic Coefficients for Strongly Starlike and Strongly Convex Functions

open access: yesAxioms, 2022
The logarithmic coefficients are very essential in the problems of univalent functions theory. The importance of the logarithmic coefficients is due to the fact that the bounds on logarithmic coefficients of f can transfer to the Taylor coefficients of ...

Sharp Bounds of Hankel Determinant on Logarithmic Coefficients for Functions Starlike with Exponential Function

open access: yesFractal and Fractional, 2022
Using the Lebedev–Milin inequalities, bounds on the logarithmic coefficients of an analytic function can be transferred to estimates on coefficients of the function itself and related functions.

On the curvature in logarithmic plots of rate coefficients for chemical reactions [PDF]

open access: yesChemistry Central Journal, 2011
In terms of the reduced potential energy barrier ζ = ΔuTS/kT, the rate coefficients for chemical reactions are usually expressed as proportional to e-ζ.

Hankel Determinants for the Logarithmic Coefficients of a Subclass of Close-to-Star Functions

open access: yesJournal of Mathematics
Suppose that ST1 is a class of close-to-star functions. In this paper, we investigated the estimate of Zalcman functional on the logarithmic coefficients and the third Hankel determinant for the class ST1 with the determinant entry of logarithmic ...

Inverse and Logarithmic Coefficient Bounds of Concave Univalent Functions

open access: yesAxioms
The 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 ...

Monotonicity and Inequalities for Ratio of the Generalized Logarithmic Means [PDF]

open access: yes, 2003
Let c > b > a > 0 be real numbers. Then the function f(r) = Lr(a,b)/Lr(a,c) is strictly decreasing on (−∞,∞), where Lr(a, b) denotes the generalized (extended) logarithmic mean of two positive numbers a and ...

Logarithmic Convexity of the One-Parameter Mean Values [PDF]

open access: yes, 2004
In this article, the logarithmic convexity of the one-parameter mean values J(r) and the monotonicity of the product J(r)J(−r) with r Є R are presented. Some more general results are established.

Functorial tropicalization of logarithmic schemes: the case of constant coefficients [PDF]

open access: yesProceedings of the London Mathematical Society, 2017
The purpose of this article is to develop foundational techniques from logarithmic geometry in order to define a functorial tropicalization map for fine and saturated logarithmic schemes in the case of constant coefficients. Our approach crucially uses the theory of fans in the sense of K.
