They are named after Abraham Adrian Albert, who pioneered the study of non-associative algebras, usually working over the real numbers. Over the real numbers, there are three such Jordan algebras up to isomorphism. One of them, which was first mentioned by Jordan, Neumann & Wigner (1934) and studied by Albert (1934), is the set of 3×3 self-adjoint matrices over the octonions, equipped with the binary operationwhere denotes matrix multiplication. Another is defined the same way, but using split octonions instead of octonions. The final is constructed from the non-split octonions using a different standard involution.Over any algebraically closed field, there is just one Albert algebra. For example, the complexifications of the three Albert algebras over the real numbers are isomorphic Albert algebras over the complex numbers. For a general field F, the Albert algebras are classified by the Galois cohomology group H1(F,G) where G is a simple split group of type F4.The Kantor–Koecher–Tits construction applied to an Albert algebra gives a form of the E7 Lie algebra.. }
