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- motivic cohomology spectrum in normed motivic spectra over the complex numbers, and find that the resultin…

Relative -Contractibility of Smooth Schemes

Adrien Dubouloz, Krishna Kumar Madhavan Vijayalakshmi, Paul Arne Østvær

We study smooth morphisms that are -contractible in the unstable -homotopy category . For base schemes of finite…

Log syntomic cohomology of truncated polynomials and coordinate axes

Doosung Park, Paul Arne Østvær

We study the logarithmic syntomic cohomology of fine and saturated log schemes and its realization in the logarithmic motivic stable homotopy category $\mathrm{logSH}(\mathrm{pt}_\…

Hermitian -theory and Milnor-Witt motivic cohomology over

Håkon Kolderup, Oliver Röndigs, Paul Arne Østvær

The theme of this paper is to compute hermitian -groups in terms of the recently developed theory of Milnor-Witt motivic cohomology. Our approach makes use of the very effective…

Cousin complexes in motivic homotopy theory

A. Druzhinin, Håkon Kolderup, Paul Arne Østvær

We investigate Cousin (bi-)complexes in the setting of motives. Over essentially smooth local schemes, the columns of the Cousin bicomplex with coefficients in any stable motivic h…

Logarithmic motivic homotopy theory

Federico Binda, Doosung Park, Paul Arne Østvær

This work is dedicated to the construction of a new motivic homotopy theory for (log) schemes, generalizing Morel-Voevodsky's (un)stable -homotopy category. Our frame…
