Biased permutative equivariant categories

Kayleigh Bangs, Skye Binegar, Young Kim +4

For a finite group G, we introduce the complete suboperad $Q_{G}$ of the categorical G-Barratt-Eccles operad $P_{G}$ . We prove that $P_{G}$ is not finitely generated, but $Q_{G}$ is finite…

The homotopy groups of the η-periodic motivic sphere spectrum

Kyle Ormsby, Oliver Röndigs

We compute the homotopy groups of the η-periodic motivic sphere spectrum over a finite-dimensional field k with characteristic not 2 and in which -1 a sum of four squares. We also…

The stable Galois correspondence for real closed fields

J. Heller, K. Ormsby

In previous work, the authors constructed and studied a lift of the Galois correspondence to stable homotopy categories. In particular, if $L / k$ is a finite Galois extension of fie…
