Moufang Sets and Structurable Division Algebras
Share this pageLien Boelaert; Tom De Medts; Anastasia Stavrova
A Moufang set is essentially a doubly transitive permutation
group such that each point stabilizer contains a normal subgroup which
is regular on the remaining vertices; these regular normal subgroups are
called the root groups, and they are assumed to be conjugate and to
generate the whole group.
It has been known for some time that
every Jordan division algebra gives rise to a Moufang set with abelian
root groups. The authors extend this result by showing that every structurable
division algebra gives rise to a Moufang set, and conversely, they show
that every Moufang set arising from a simple linear algebraic group of
relative rank one over an arbitrary field \(k\) of characteristic
different from \(2\) and \(3\) arises from a structurable
division algebra.
The authors also obtain explicit formulas for the root
groups, the \(\tau\)-map and the Hua maps of these Moufang sets.
This is particularly useful for the Moufang sets arising from
exceptional linear algebraic groups.
