Approximation of the Hersch-Pfluger distortion function. (English) Zbl 0793.30013
This paper aims at giving a method of approximating the distortion function \(\Phi_ K\) by means of elementary functions. As a consequence, new bounds for the function \(\Phi_ K\) are established. Moreover, the \(n\)-dimensional counterpart \(\Phi_{K,n}\) of \(\Phi_ K\), \(n=2,3,\dots\) is considered.
