Jordan and isometric cone automorphisms in Euclidean Jordan algebras
Every symmetric cone K arises as the cone of squares in a Euclidean Jordan algebra V. As V is a real inner-product space, we may denote by Isom(V) its group of isometries. The groups JAut(V) of its Jordan-algebra automorphisms and Aut(K) of the linear cone automorphisms are then related. For certain inner products, JAut(V) = … Read more
