<p class="MsoNormal" style="margin-bottom:12.0pt;background:white"><span style="font-size:11.5pt;font-family:"Segoe UI",sans-serif;color:black">In the first talk, I will review the classical work of Atiyah and Singer describing the homotopy type of the family
of Dirac operators on a spin Riemannian manifold, and its consequences regarding metrics of positive scalar curvature. In the second talk, I will discuss how one can exploit the Seiberg-Witten equations and Floer theory to obtain more detailed information
about the structure of the family in the case of a three-manifold for which the spectral gap of the Hodge Laplacian on coexact 1-forms is large compared to the curvature. For concreteness, we will have a special focus on the case of the n-torus throughout
the talks.</span><o:p></o:p></p>
