摘要:We study small covers and the real moment-angle manifold over a simple polytope that admit Riemannian metrics of positive scalar curvature. We first explain some general facts on the existence of positive scalar curvature on a smooth manifold.Then we show a class of simple polytopes over which the small covers and the real moment-angle manifolds

admit metrics of positive scalar curvature.In particular, these examples give all the 3-dimensional small covers that admit metrics of positive scalar curvature.
