Talk:Hegerfeldt's theorem

Is this a notable topic?
I'm sorry, but I must question the notability of this article. The original papers have (depending on where you look, NASA ADS or INSPIRE; Google scholar gives it a bit more) citations in the double digits, which does not quite seem enough. Of course this is an area of philosophy of physics which overall gets fewer citations than other areas. But still, my personal approach is usually that the lower limit is something approaching a few hundred citations for HEP things. I am all for having articles on obscure (but still notable) physics topics, but I'm a bit unsure about this one (although the theorem itself is quite cool). Maybe it comes down to the disconnect between philosophy of physics citation numbers versus HEP citation numbers (I'm used to the latter category). Certainly notable math topics get far fewer citations than notable physics ones for example. So generally, I'm leaning towards it staying. OpenScience709 (talk) 20:54, 12 December 2022 (UTC)

Wrong Dates. It's 1974, not 1998
Hegerfeldt's theorem was known long before 1998. It was a key element in the framework laid out by Prugovečki, and was used and cited in many places by him, such as in his Stochastic Quantum Mechanics and Quantum Spacetime (1984) (https://link.springer.com/book/10.1007/978-94-009-4492-3) as Hegerfeldt G. C.: 1974, ''Phys. Rev.'' D10, 3320 (https://journals.aps.org/prd/abstract/10.1103/PhysRevD.10.3320). A framework for POVM-based localization is also laid out and used by Prugovečki therein, and elsewhere, and is one of the central elements of his framework. — Preceding unsigned comment added by 2603:6000:AA00:151F:0:0:0:193B (talk) 20:41, 14 February 2024 (UTC)
