We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Omori-Yau maximum principles, V-harmonic maps and their geometric applications
Qun Chen, Jürgen Jost and Hongbing Qiu
Abstract
We establish a V-Laplacian comparison theorem under the Bakry--Emery Ricci condition and then give various Omori--Yau type maximum principles on complete noncompact manifolds. We also obtain Liouville theorems for $V$-harmonic maps. We apply these findings to Ricci solitons and self-shrinkers.
