Simultaneous Diophantine Approximation Using Primes

Bulletin of the London Mathematical Society, 1988
The authors consider k-tuples of reals \((\alpha_ 1,...,\alpha_ k)\) which satisfy the compatibility condition: If \(h_ i\in {\mathbb{Z}}\) for \(1\leq i\leq k\) and \(\sum^{k}_{i=1}h_ i\alpha_ i\in {\mathbb{Q}}\) then \(\sum^{k}_{i=1}h_ i\alpha_ i\in {\mathbb{Z}}\).

Robust Simultaneous Sparse Approximation

2015
This chapter considers sparse underdetermined (ill-posed) multivariate multiple linear regression model known in signal processing literature as multiple measurement vector (MMV) model. The objective is to find good recovery of jointly sparse unknown signal vectors from the given multiple measurement vectors which are different linear combinations of ...

Simultaneous Approximation in Positive Characteristic

Monatshefte f�r Mathematik, 2000
The authors generalise Diophantine approximation results of Voloch and de Mathan in positive characteristic to higher dimensions. Let \(k\) be field of characteristic \(p>0\) and put \(R=k[X]\), \(K=k(X)\), \({\mathcal K}=k((X^{-1}))\). We endow \({\mathcal K}\) with a non-archimedean absolute value \(|\cdot |\), such that for \(\alpha =\sum_{n=t ...

L∞ norm simultaneous system approximation

International Journal of Robust and Nonlinear Control, 1996
In this paper the L∞ norm optimal simultaneous system approximation problem is studied. Various LMI based approaches to solve the simultaneous L∞ norm system approximation problem are developed. Computational schemes based on LMI based optimization techniques are derived. Examples are given to illustrate the results.

Simultaneous Diophantine Approximation To Series

Journal of the London Mathematical Society, 1959
Es sei \(\mathfrak K\) die Menge aller formalen Laurentreihen \(x = \alpha_d z^d + \alpha_{d-1}z^{d-1}+ \ldots\) mit Koeffizienten aus einem Körper \(\mathfrak k\). Es werde ferner \(\mathfrak T = \mathfrak k [z]\) und \(\mathfrak R = \mathfrak k(z)\) gesetzt.

Best Simultaneous Approximation

1984
Publisher Summary This chapter considers (F, e· e) as a nontrivial nonarchimedean valued division ring and (E, ee· ee) is a nonzero nonarchimedean normed space over (F, e· e). The chapter discusses a problem that in the nonarchimedean case has a very simple solution: when M ≠ {O}, there is no uniqueness.
