TITLE: Famous cases of multiple papers by the same author published in same issue of same journal
QUESTION [6 upvotes]: I have been wondering if there are many cases of an author having published two (or more?) papers in the same issue of the same journal. I vaguely recall having seen one or two cases like this, maybe be old papers, but cannot vividly remember. I have the impression such a situation would make sense should the two papers be in the same topic, say, one is sort of a (substantial) continuation of the other, for instance (given the fact that in Mathematics there is some pressure against publishing too often in the same journal). I am of course asking this question for papers having a sole author (or maybe the same set of authors).

REPLY [6 votes]: Edoardo Ballico published (until now) 404 articles in the International Journal of Pure and Applied Mathematics. He published many times two or more articles in the same issue.
For instance, in 2009 he published four articles in "Int. J. Pure Appl. Math. 57 (2009), no. 4,"
