Jordan algebras are quite from things I know about - I'll just mention that a tag-info for the jordan-algebras tag has been suggested recently: 87527, 87528.

Let $J$ be an unital Jordan algebra (over $\mathbb{R}$) - recall that this means that $J$ is an unital $\mathbb{R}$-algebra (whose product we denote by $\bullet$) satisfying $x\bullet y=y\bullet x$ and $(x^{\bullet 2}\bullet y)\bullet x=x^{\bullet 2}\bullet(y\bullet x)$ (where $x^{\bullet 2}=x\bu...

Indecomposable symmetric cones fall into five classes. The automorphism group of any symmetric cone $C$ is a real Lie group $Aut(C)$. What is the associated class of Lie groups $Aut(C)$ for each of the five classes of indecomposable symmetric cones?
At math.SE there also is a jordan algebras tag with 8 questions and empty tag-info. So if somebody confirms the the tag-info suggested here looks good, it could probably be copied to the other side, too.

To be on the safe side, I ask before editing, but to me it seems that harmonic-functions would be more suitable here than harmonic-analysis. (The latter was introduced in this suggested edit.) Functions orthogonal to harmonic functions
