$\mathbb{E}_\infty$ automorphisms of motivic Morava $E$-theories

Published 17 Jan 2019 in math.KT and math.AT | (1901.05713v1)

Abstract: We apply Goerss--Hopkins obstruction theory for motivic spectra to study the motivic Morava $E$-theories. We find that they always admit $\mathbb{E}\infty$ structures, but that these may admit "exotic" $\mathbb{E}\infty$ automorphisms not coming from the usual Morava stabilizer group.
