Motivic Hochschild homology of mod 2 motivic cohomology over algebraically closed fields

Tom Bachmann, Robert Burklund, Bjørn Ian Dundas +1

We compute the tensor of the multiplicative group scheme with the mod- $2$ motivic cohomology spectrum in normed motivic spectra over the complex numbers, and find that the resultin…

Relative $A^{1}$ -Contractibility of Smooth Schemes

Adrien Dubouloz, Krishna Kumar Madhavan Vijayalakshmi, Paul Arne Østvær

We study smooth morphisms $f : X \to S$ that are $A^{1}$ -contractible in the unstable $A^{1}$ -homotopy category $H (S)$ . For base schemes $S$ of finite…
