Boundary Metric from Projection-Induced Finite Rank
Pasquale Camelia · Zenodo (CERN European Organization for Nuclear Research) · 2025
This work investigates the notion of metric induced by finite-rank projection.Assuming a non-isometric projection with finite effective rank, the paper showsthat a unique operational boundary metric emerges as a criterion ofdistinguishability, determined by the truncated singular value decomposition.This is a preliminary, pre-review version made publicly available on Zenodo.
