Separating G_2-invariants of several octonions (2209.12620v2)
Published 6 Sep 2022 in math.RA, math.AG, and math.RT
Abstract: We describe separating G_2-invariants of several copies of the algebra of octonions over an algebraically closed field of characteristic two. We also obtain a minimal separating and a minimal generating set for G_2-invariants of several copies of the algebra of octonions in case of a field of odd characteristic.
