Errata: Presentations of the mapping class group
In [Isr. J. Math. 45, 157-174 (1983; Zbl 0533.57002)] the second author gave a presentation for the mapping class group \(M_{n,k}\) of an orientable surface \(F_{n,k}\) of genus \(n\geq 1\) with \(k=0\) or 1 boundary components. The statement of Theorem 2 in that paper contains an error. In this note we correct the error. At the same time we correct inaccuracies in [the authors, Lect. Notes Math. 1167, 24-46 (1985; Zbl 0589.57009)], which studied the same circle of ideas and made use of results from the paper cited at the beginning.
