Abstract
1. Investigating semi-discrete methods for the numerical treatment of heat-conduction problems Cody, Meinardus & Varga [1] studied the uniform approximation of e−x by rational functions. More precisely, denoting by Πn the collection of all real polynomials of degree at most n and by \(||.|{|_{{{L_{\infty }}[0,\infty )}}} \) the supremumnorm on the positive real axis they asked for
