Uniform Diophantine approximation and best approximation polynomials

Johannes Schleischitz

Let $ζ$ be a real transcendental number. We introduce a new method to find upper bounds for the classical exponent $w_{n} (ζ)$ concerning uniform polynomial approximation.…

An equivalence principle between polynomial and simultaneous Diophantine approximation

Johannes Schleischitz

We show that Mahler's classification of real numbers $ζ$ with respect to the growth of the sequence $(w_{n} (ζ))_{n \geq 1}$ is equivalently induced by certain natural assumptions on…

Diophantine approximation in prescribed degree

Johannes Schleischitz

We investigate approximation to a given real number by algebraic numbers and algebraic integers of prescribed degree. We deal with both best and uniform approximation, and highligh…

On the discrepancy between best and uniform approximation

Johannes Schleischitz

For $ζ$ a transcendental real number, we consider the classical Diophantine exponents $w_{n} (ζ)$ and $w_{n} (ζ)$ . They measure how small $∣ P (ζ) ∣$ can be for an integer po…
