Minimizers of the sharp Log entropy on manifolds with non-negative Ricci curvature and flatness
Qi S Zhang
Consider the scaling invariant, sharp log entropy (functional) introduced by Weissler \cite{W:1} on noncompact manifolds with nonnegative Ricci curvature. It can also be regarded a…

Fundamental Gap of Convex Domains in the Spheres (with Appendix B by Qi S. Zhang)
Chenxu He, Guofang Wei
In [SWW], S. Seto, L. Wang and G. Wei proved that the gap between the first two Dirichlet eigenvalues of a convex domain in the unit sphere is at least as large as that for an asso…

Bounds on harmonic radius and limits of manifolds with bounded Bakry-Émery Ricci curvature
Qi S Zhang, Meng Zhu
Under the usual condition that the volume of a geodesic ball is close to the Euclidean one or the injectivity radii is bounded from below, we prove a lower bound of the $C^α W^{1,…
