This talk deals with<br>scalar curvature, which can be defined by the volume growth of small<br>balls in Riemannian manifolds. We give an overview of some old and new<br>results concerning Riemannian metrics with everywhere positive scalar<br>curvature, combining techniques from global analysis, topology, and<br>general relativity.<br><br>There will be tea and biscuits after the talk<br></span><span style="-webkit-text-size-adjust: auto;"></span><br style="-webkit-text-size-adjust: auto;"></div><div>---------</div></body></html>
