Sub-Riemannian Ricci curvature via generalized Gamma calculus

Qi Feng, Wuchen Li

We derive sub-Riemannian Ricci curvature tensor for sub-Riemannian manifolds. We provide examples including the Heisenberg group, displacement group, and Martinet sub-Riemannian st…

Entropy dissipation for degenerate stochastic differential equations via sub-Riemannian density manifold

Qi Feng, Wuchen Li

We study the dynamical behaviors of degenerate stochastic differential equations (SDEs). We select an auxiliary Fisher information functional as the Lyapunov functional. Using gene…

Harnack inequalities on totally geodesic foliations with transverse Ricci flow

Qi Feng

In the current paper,under the transverse Ricci flow on a totally geodesic Riemannian foliation, we prove two types of differential Harnack inequalities (Li-Yau gradient estimate)…
