# a problem in functional analysis that erdos solved in 2 lines

does anyone know about what the problem was and what was his solution.

May be that was a half-page proof that $\pi$ is transcendental using $\Gamma$-functions? –  Victor Mar 1 '13 at 7:31
@Victor: Hmmm..I would rather consider $\Gamma$-functions as part of real analysis than Functional Analysis. –  S.C. Mar 1 '13 at 7:39
Dear Koushik, if you had added more context to the question, we could have avoided some unnecessary speculation among the commenters who didn't bother to click through. –  S. Carnahan Mar 1 '13 at 8:29
This should be closed in favor of the stack exchange question, in light of the quality of the answers there. It's hard to do much better than have the actual source of the anecdote answer. –  arsmath Mar 1 '13 at 20:18
This should absolutely not be closed, because we still don't know what the problem was, much less P.E.'s solution! The information given at mathstackexchange was curiously and frustratingly incomplete. –  Todd Trimble Mar 2 '13 at 2:11
