Degree of Simultaneous Coconvex Polynomial Approximation
Results in Mathematics, 1998Let \(f\in C^1[-1,1]\) change its convexity \(s\)-times at the points \(y_j\in (-1,1)\) \((j-1, \dots,s)\). Then \(f\) is approximated by polynomials \(p_n\), which are coconvex with \(f\), i.e., \(p_n\) changes its convexity exactly at the same points \(y_j\) \((j=1, \dots,s)\).

On the Degree of Approximation in Multivariate Weighted Approximation
, 2002Let s ≥ 1 be an integer, f ∈ L P (R s ) for some p, 1 ≤ p ∞ or be a continuous function on R S vanishing at infinity. We consider the degree of approxima-tion of f by expressions of the form exp \( ( - {\text{ }}\sum\limits_{k = 1}^s {{Q_k}\left( {{x_k}} \right)} )P\left( {{x_1},...,{x_s}} \right) \) where each exp(—Q k (·)) is a Freud type weight ...

Degree of Approximation of Hölder Continuous Functions
Mathematische Nachrichten, 1989Recently, the present reviewer and the present author [Approximation Theory Appl. 4, No.2, 49-54 (1988; Zbl 0673.42002)] have applied \((J,q_ n)\)-transform to determine the degree of approximation of functions \(f\in L_ p\quad (p\geq 1)\) in \(L_ p\)-norm.

Low-degree approximation of high-degree B-spline surfaces
Engineering with Computers, 1993In this paper, a method for approximate conversion of high degree Bezier and B-spline surfaces to lower degree representations is presented to facilitate the exchange of surface geometry between different geometric modeling systems. Building on previous work on curve approximation, the method uses adaptive sampling to compute approximation error and ...
