The Magic Square and Symmetric Compositions

Alberto Elduque[1]

(1) Universidad de Zaragoza, Spain

The new construction given by Barton and Sudbery of the Freudenthal-Tits magic square, which includes the exceptional classical simple Lie algebras, will be interpreted and extended by using a pair of symmetric composition algebras, instead of the standard unital composition algebras.

Keywords: Freudenthal Tits magic square, symmetric composition algebra, exceptional Lie algebras
