Polynomials of Least Deviation from Zero in Sobolev p-Norm [PDF]
AbstractThe first part of this paper complements previous results on characterization of polynomials of least deviation from zero in Sobolev p-norm ($$1<p<\infty $$ 1 < p < ∞ ) for the ...

POLYNOMIALS LEAST DEVIATING FROM ZERO IN \(L^p(-1;1)\), \(0 \le p \le \infty \), WITH A CONSTRAINT ON THE LOCATION OF THEIR ROOTS [PDF]
We study Chebyshev's problem on polynomials that deviate least from zero with respect to \(L^p\)-means on the interval \([-1;1]\) with a constraint on the location of roots of polynomials.

Trigonometric polynomials of least deviation from zero in measure and related problems
Let \(\mathcal{F}_{n}\) be the set of trigonometric polynomials \[ f_{n}(t)=\frac{a_{0}}{2}+\sum_{k=1}^{n}(a_{k}\cos kt +b_{k}\sin k t) \] of order \(n\geq 0\) with real coefficients. On the set \(\mathcal{F}_{n}\) consider the functional \[ \mu(f_{n})=\text{mes}\{t\in \mathbb{T}\,:\,|f_{n}(t)|\geq 1\}, \] where \(\text{mes}\) stands for the Lebesgue ...

On multivariate polynomials of least deviation from zero on the unit cube
AbstractIn the family of all r-variable real polynomials with total degree not exceeding μ and with maximum norm on the unit-cube not exceeding 1, any of the leading coefficients is maximum for a special product of one-variable Chebyshev polynomials of the first kind.

Explicit algebraic solution of Zolotarev's First Problem for low-degree polynomials
E.I. Zolotarev's classical so-called First Problem (ZFP), which was posed to him by P.L. Chebyshev, is to determine, for a given \(n\in{\mathbb N}\backslash\{1\}\) and for a given \(s\in{\mathbb R}\backslash\{0\}\), the monic polynomial solution \(Z ...

Short-Arc Horizon-Based Optical Navigation by Total Least-Squares Estimation
Horizon-based optical navigation (OPNAV) is an attractive solution for deep space exploration missions, with strong autonomy and high accuracy. In some scenarios, especially those with large variations in spacecraft distance from celestial bodies, the ...

Motor errors can have both bias and noise components. Bias can be compensated for by adaptation and, in tasks in which the magnitude of noise varies across the environment, noise can be reduced by identifying and then acting in less noisy regions of the ...
