The prime-to-p part of étale fundamental groups of curves
arXiv:1209.3693
Abstract
The previous version of this paper relied on a paper by another author whose proof appears to be invalid in a fundamental way. In arXiv:1707.00649 the author, together with Jeff Yelton, came up with a new proof of almost identical results. (See Remark 1.4 of arXiv:1707.00649.)
