The etale Tits process of Jordan algebras revisited
It is shown that any absolutely simple Jordan algebra J
of degree 3 and dimension 9 can be reached by the etale Tits
process from any cubic etale subalgebra. Criteria for two etale
Tits processes to be isomorphic are also given. As an application,
embeddings from a fixed cubic etale algebra into J up to eqivalence
are classified by their norm classes.
