%0 Journal Article %T A note on the Lichnerowicz vanishing theorem for proper actions %A Weiping Zhang %J Mathematics %D 2015 %I arXiv %X We prove a Lichnerowicz type vanishing theorem for non-compact spin manifolds admiting proper cocompact actions. This extends a previous result of Ziran Liu who proves it for the case where the acting group is unimodular. %U http://arxiv.org/abs/1506.02968v1
