Erratum to "The loop space of the Q-construction", by Daniel R. Grayson and Henri Gillet

We have posted (July, 2002) an improved version of the erratum, which gives a completely combinatorial approach to Theorem B' of the paper (a simplicial analogue of Quillen's Theorem B).

Lemma 1.5 of the original paper is not true, but a slightly weaker version is true and suffices for the applications in the paper. We prove the weaker version in this erratum.
