摘要
The duality in Bakry-A parts per thousand mery's gradient estimates and Wasserstein controls for heat distributions is extended to that in refined estimates in a high generality. As a result, we find an equivalent condition to Bakry-Ledoux's refined gradient estimate involving an upper dimension bound. This new condition is described as a -Wasserstein control for heat distributions at different times. The -version of those estimates are studied on Riemannian manifolds via coupling method.
