While going through a forum post (http://mathforum.org/kb/message.jspa?messageID=40112), I found the following paper mentioned:
87a:12014 12J10 13A18 Ribenboim, Paulo (3-QEN) Equivalent forms of Hensel's lemma. (English)
Exposition. Math. 3 (1985), no. 1, 3--24.
I have been unable to find the paper mentioned. Can someone help me obtain a digital copy of this paper? Please let me know, and apologies if this isn't the right forum to pose this question.
