Abstract:
I had a short conversation with Richard Montgomery. It led to a surprising connection between Ricci curvature and sub-Riemannian geometry: Pan-Wei's example of Ricci limit space is isometric to half of the Grushin plane, a classical example in sub-Riemannian geometry. Inspired by this connection, we construct the Grushin hemisphere as a Ricci limit space with curvature >=1.
