Comonotone approximation of \(|X|\) by rational functions
1983It is shown that the rational approximant r(x)\(\in {\mathcal R}^ n_ n[- 1,1]\) introduced by Newman satisfying \(| | x| -r(x)| \leq 3\bar e^{\sqrt{n}}\) is actually a comonotone approximation of \(| x|\) on [-1,1] in that r'(x)\(\leq 0\) for \(x\in [-1,0]\) and r'(x)\(\geq 0\) for \(x\in [0,1]\). Furthermore, it is shown that the result of Vyaceslavov
