Several important results used in at least three different areas (metric embeddings and approximation algorithms; constructions of various kinds of extractors; and PCP constructions for hardness of approximation results) appeared there. And, increasingly, theoreticians are publishing their own papers in GAFA. (Mostly on PCP-related and embeddings-related stuff.)<BR/><BR/>What's next? Maybe ten years from now we will start hearing "Atiyah", "Langlands", "sheaf" and "cohomology" as often as we now hear "Bourgain", "ell-two" and so on.Lucahttps://www.blogger.com/profile/17835412240486594185noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-1129867492477229022005-10-20T23:04:00.000-05:002005-10-20T23:04:00.000-05:00I thought ints were Z_{2^32}.I thought ints were Z_{2^32}.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-1129865491704563192005-10-20T22:31:00.000-05:002005-10-20T22:31:00.000-05:00Hmmm, this prompts my memory from last week when I...Hmmm, this prompts my memory from last week when I was wondering what the hell an int would be, as they aren't closed under much, at least not so long as there're monkeys pounding on assemblers!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-1129861622955505112005-10-20T21:27:00.000-05:002005-10-20T21:27:00.000-05:00No "graph theory" in your list?

If it is, what else is there (other than combinatorics) in discrete math? (Discrete probability ? :-))Anonymousnoreply@blogger.com
