Isotopes of Hurwitz algebras
Erik Darpö
We study the class of all algebras that are isotopic to a Hurwitz algebra. Isomorphism classes of such algebras are shown to correspond to orbits of a certain group action. A compl…

Normal forms for the G_2-action on the real symmetric 7x7-matrices by conjugation
Erik Darpö
The exceptional Lie group G_2 acts on the set of real symmetric 7x7-matrices by conjugation. We solve the normal form problem for this group action. In view of earlier results, thi…
