I know I've seen a very short article (3-5 pages) with a proof of a spectral theorem for rigged Hilbert spaces, written for people who already know the usual spectral theorems, by some guy who I think had a muslim name. Anyone know what I'm talking about? It's been posted here before, almost certainly more than once, but I just spent 20 minutes trying to find it here and on my computer, so I think it's time to just ask. No need to hurry to get me an answer right away. I'm not even going to read it right away. I'm just making a to-do list about things I'd like to understand better, and I want to put this article on the list. (I think I may even have asked this question before, LOL).
