Ricci flow for the Bures--Helstrom qubit metric

Collection of recent arXiv submissions (math/IT and related fields) covering: an explicit Ricci flow solution for the Bures–Helstrom qubit metric and its spectral properties; a lightweight ML pipeline for BLE direction-finding LOS/NLOS detection using robust standardization, Nyström kernel approximation and an SVC head; a parity selection rule linking mutual information and entropy production in driven steady states; the introduction of Doeblin curves for refined multi-way contraction analysis with applications to optimization, noisy computation, and differential privacy; site-specific MIMO RF
