| Popis: | The octonion torus (or Cayley torus) appears as a coordinate algebra of extended affine Lie algebras of type A 2 and F 4 . A generalized version of the octonion torus, called division Z n -graded alternative algebras, is classified in this paper. Using the result, we can complete the classification of division ( A 2 , Z n ) -graded Lie algebras, up to central extensions, which are a generalization of the cores of extended affine Lie algebras of type A 2 . |
