Abstract: We will go over the surgery procedure adapted by R. Schoen and S.-T. Yau in their article: On the structure of manifolds with positive scalar curvature, Manuscripta Math. 28, (1979), 159-183. The goal of this surgery is to prove that any manifold constructed from doing connected sum along submanifolds (with codimension greater or equal to 3) of two manifolds with positive scalar curvature also admits a metric with positive scalar curvature.
