The complex motivic kq-resolution
Mahowald calculated the 2-primary image of J and proved the Telescope Conjecture at height one using the bo-based Adams spectral sequence. I will discuss analogous applications in the complex motivic setting using the kq-based Adams spectral sequence, where kq is the very effective cover of hermitian K-theory. This is work in progress with Dominic Culver.

Recent developments in the Riemann-Roch theorem
In this talk we will review some classic questions posed by Grothendieck and others around the Riemann-Roch theorem. Afterwards, we will explain how the Riemann-Roch fits into Panin's orientation theory and how motivic homotopy theory and Gabber's work on absolute purity have developed the Riemann-Roch theorem. Finally, we will speak about the lift of the Riemann-Roch into integral coefficients.

The DG-category of secondary cohomology operations
In joint work with Hans-Joachim Baues, we study track categories (i.e., groupoid-enriched categories) endowed with additive structure similar to that of a 1-truncated DG-category, except that composition is not assumed right linear. We show that if such a track category is right linear up to suitably coherent correction tracks, then it is weakly equivalent to a 1-truncated DG-category. This generalizes work of Baues on the strictification of secondary cohomology operations. As an application, we show that the secondary integral Steenrod algebra is strictifiable.
