Simultaneous approximation of algebraic numbers

Mathematical Notes, 1992
Let 1, \(\theta_ 1, \dots, \theta_ s\) \((s \geq 2)\) be a basis of a purely algebraic field \(\mathbb{K}\) of degree \(s+1\). The author proves the following theorem: assume that a natural number simultaneously approximates the number \(\theta_ 1, \dots, \theta_ s\), \[ \| q \theta_ i \| = \min_{a \in \mathbb{Z}} | q \theta_ i - a |0\) is some ...

On a simultaneous approximation of logarithms and algebraic powers of algebraic numbers

Mathematical Notes, 1994
Let \(\theta\in \mathbb{C}\) be an arbitrary transcendental number. Denote \(\mathbb{Q}_1= \mathbb{Q}(\theta)\) and \(\mathbb{J}_1= \mathbb{Z}[\theta]\). Let \(\mathbb{Q}^*_1\) be an algebraic extension of \(\mathbb{Q}_1\) of finite degree generated by the numbers \(\theta\) and \(\omega_1\), where \(\omega_1\) is a root of an irreducible polynomial in

RATIONAL APPROXIMATIONS TO ALGEBRAIC NUMBERS

Mathematika, 1955
This important paper contains a proof of the long conjectured theorem: ``If \(\alpha\) is an algebraic irrational number, and if there are infinitely many fractions \(h/q\) with \(\vert \alpha - h/q\vert \le q^{-\kappa}\), \(q > 0\), \((h, q) = 1\), then \(\kappa\le 2\).'' Much of the proof runs on classical lines.

APPROXIMATING NUMBERS OF THE CANTOR SET BY ALGEBRAIC NUMBERS

Bulletin of the Australian Mathematical Society, 2022
AbstractWe consider the set of elements in a translation of the middle-third Cantor set which can be well approximated by algebraic numbers of bounded degree. A doubling dimensional result is given, which enables one to conclude an upper bound on the dimension of the set in question for a generic translation.

Rational quadratic approximation to real algebraic curves

Computer Aided Geometric Design, 2004
An algorithm is proposed to give a global approximation of an implicit real plane algebraic curve with rational quadratic B-spline curves. The algorithm consists of four steps: topology determination, curve segmentation, segment approximation and curve ...
