Title: Surgery, bordism and scalar curvature

Abstract: One of the most influential results in scalar curvature geometry, due to Gromov-Lawson and Schoen-Yau, is the construction of metrics with positive scalar curvature by surgery. Combined with powerful tools from geometric topology, this has strong implications for the classification of such metrics. We will give an overview of the method and point out some recent developments.
