Topic: sheaf-theoretic approach to relativistic physics?

view this post on Zulip Naso (Sep 12 2022 at 01:47):

Is there a sheaf-theoretic approach to relativistic physics? Stuff like Relativity of simultaneity and Lack of an absolute reference frame sounds vaguely like a statement that a certain sheaf lacks global sections.

There's a copresheaf-theoretic approach to relativistic quantum field theory, which is actually pretty popular, but there people use a copresheaf of operator algebras on Minkowski spacetime.
