Let A be a JBW-algebra admitting a faithful normal finite trace. Given a convex function \(M: {\mathbb{R}}^+\to {\mathbb{R}}^+\) the author defines the corresponding Orlicz space \(L_ M(A)\) in \(L^ 1(A)\). The characterization of Orlicz spaces is based on a structure called Banach ordered Jordan algebroid. No proofs are included.
