Summary

In this paper, Mahler introduces a method of transcendence now known as Mahler's method. He applies his method to show that the numbers \par \[ \par \par \sum_{n\ge 0} t(n)\alpha^n\quad\mbox{and}\quad\sum_{n\ge 0}\lfloor n\omega\rfloor \alpha^n \par \par \] \par are transcendental for any algebraic number \(\alpha\) with \(0<|\alpha|<1\) and any positive quadratic irrational number \(\omega\), where \(\{t(n)\}_{n\ge 0}\) is the Thue-Morse sequence with values in \(\{-1,1\}\) and \(\rfloor x\lfloor\) denotes the integer part of \(x\). \par This article is the first in a series of three papers that develops Mahler's method. \par Reprint of the author's paper [Math.
