A holonomy action for U(1) gauge fields on causal sets, II: the 3+1-dimensional constant-field mean, the variance obstruction, and the capped L² window
Paper II of two. Paper I (10.5281/zenodo.23010937, Version 3) defines the action and proves the 1+1-dimensional theorems. This paper treats d ≥ 3. Provenance: its content is the higher-dimensional part of the earlier single manuscript (Versions 1–2 of the Paper I record), revised after two external audits, an internal...
