Since the paper by J.-E. Roos in Sémin. d’algèbre P. Dubreil, Proc., Paris 1977/78, Lect. Notes Math. 740, 285-322 (1979; Zbl 0415.13012) there has been an intense study on the analogy between rational homotopy theory in topology and homology of local rings in algebra. This paper is written by two of the main contributors to this study. It contains an overview of old and new results and a dictionary on the interplay between the two subjects.
