Title: Slant products on the analytic structure group via the stable Higson corona

Abstract: We show injectivitiy of certain exterior product maps on the K-theory of the Roe algebra and the analytic structure group by a partial pairing (or "slant product") with the K-theory of the stable Higson corona. We will explore applications in primary and secondary index theory, in particular to positive scalar curvature. This is ongoing joint work with Alexander Engel and Christopher Wulff.
