Uniform Convergence of Some Extremal Polynomials in Domain with Corners on the Boundary

open access: yesJournal of Inequalities and Applications, 2010
The aim of this paper is to investigate approximation properties of some extremal polynomials in Ap1, p>0 space. We are interested in finding approximation rate of extremal polynomials to Riemann function in Ap1 and C-norms on domains bounded by ...

Interpolation of Weighted Extremal Functions [PDF]

open access: yesArnold Mathematical Journal, 2021
AbstractAn approach to interpolation of compact subsets of$${{\mathbb {C}}}^n$$Cn, including Brunn–Minkowski type inequalities for the capacities of the interpolating sets, was developed in [8] by means of plurisubharmonic geodesics between relative extremal functions of the given sets.

Optimal recovery of derivatives of Hardy class functions [PDF]

open access: yesE3S Web of Conferences, 2019
The paper considers the best linear method for approximating the values of derivatives of Hardy class functions in the unit circle at zero according to the information about the values of functions at a finite number of points z1,...,zn that form a ...

Characterizing extremal coefficient functions and extremal correlation functions

open access: yes, 2012
We focus on two dependency quantities of a max-stable random field $X$ on some space $T$: the extremal coefficient function $θ$ which we define on finite sets of $T$ and the extremal correlation function $χ(s,t)=\lim_{x \uparrow \infty} \PP(X_s \geq x \mid X_t \geq x)$.

Inequalities for analytic functions associated with hyperbolic cosine function

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
In this paper, we investigate the geometric properties of a specific subclass of analytic functions satisfying  the condition f' (z) ≺ cosh(√ z) meaning that the function f '(z) is subordinate to the function cosh(√ z).

Extremal Graphs to Vertex Degree Function Index for Convex Functions

open access: yes, 2022
The vertex-degree function index Hf(Γ) is defined as Hf(Γ)=∑v∈V(Γ)f(d(v)) for a function f(x) defined on non-negative real numbers.

Extremal functions for sequences

open access: yesDiscrete Mathematics, 1996
This paper deals with a certain kind of finite sequences of symbols having no immediate repetition and with no alternating subsequence of length \(s\). Strong upper and lower bounds on the maximum length of such sequences with \(n\) symbols are well known. In this paper the author discusses some properties of the generalization of this concept and goes
