Deterministic--Distance Couplings of Brownian Motions on Radially Isoparametric Manifolds

Gunhee Cho, Hyun Chul Jang, Taeik Kim

We develop a unified geometric framework for coadapted Brownian couplings on radially isoparametric manifolds (RIM)--spaces whose geodesic spheres have principal curvatures $κ_1(r…
