What it is

Non-associative but commutative algebraic structure devised by Pascual Jordan to formalize quantum-mechanical observables; it gave rise to its own mathematical theory.

What it led to

  • Algebraic formalization of quantum mechanics
  • Classification of Jordan algebras (Jordan–von Neumann–Wigner)
  • Applications in geometry and exceptional Lie groups
  • Development of non-associative algebras
