questions using homotopy theory. In joint work with Sarah Yeakel, we are developing a program to study manifold topology via isovariant homotopy theory. I'll explain what isovariant homotopy theory is and how it relates to the study of manifolds via their
configuration spaces, and talk about an application to fixed point theory.</span><span lang="EN-US" style="font-size:12.0pt;color:black"><o:p></o:p></span></p>

the other largely conjectural. Time permitting I will lay out a strategy for remedying some of the conjectural nature of the latter approach.</span><b><span lang="EN-US" style="mso-fareast-language:EN-US"><o:p></o:p></span></b></p>
