    Demuth's path to randomness (English)
    0 references
    This article surveys the work of Osvald Demuth, in particular, the notions of random real that he examined. The authors emphasize that Demuth was motivated by considerations of Russian-school constructive analysis, and he described these notions in terms of approximability, rather than randomness. This paper is based on an extended abstract written by \textit{A. Kučera} and \textit{A. Nies} [Lect. Notes Comput. Sci. 7160, 159--173 (2012; Zbl 1353.03047)]. However, the present version roughly triples the length of the earlier one, providing more background material and covering a wider span of Demuth's output.
