The Bezoutian of a Rational Function

Daniel Carmody   [email] (UIUC Math)

Abstract: The computation of the pointed endomorphisms of $\mathbb P^1$ gives a first approximation to the zeroth stable homotopy group of the motivic sphere. In this introductory talk, following Cazanave, Iíll give some examples of a basic construction which associates a bilinear form to a rational function $\mathbb P^1 \rightarrow \mathbb P^1$. This will hint at a reason for the appearance of Grothendieck-Witt groups in stable motivic homotopy theory.

Von Neumann Dimension and W*-Modules

Marius Junge (UIUC)

Abstract: We start our investigation on L2 Betti numbers by analyzing Hilbert modules over von Neumann algebras and their dimension function.
