Query: Extensions of Bonnet-Myers' type theorems with the Bakry-Emery Ricci
  curvature   In this paper, we prove the extensions of Bonnet--Myers' type theorems
obtained by Calabi and Cheeger--Gromov--Taylor via Bakry--Emery Ricci
curvature, which generalize the results of \cite{FG, Lim1, Wan, Wang, WW, Wu}.
