This is the first of what will be a sequence of three papers dealing with a generalization of certain parts of the beautiful work of V. Kac on finiteorder automorphisms of finite-dimensional complex simple Lie algebras. Recall that Kac (see [K2, Chap. 8] and [H, Sect. X.5]) built a Lie algebra from

Presented here is a construction of certain bases of basic representations for classical affine Lie algebras. The starting point is a -ޚgrading ᒄ s ᒄ q ᒄ q ᒄ y1 0 1 of a classical Lie algebra ᒄ and the corresponding decomposition ᒄ s ᒄ q ᒄ q ˜˜ỹ 1 0 ᒄ of the affine Lie algebra ᒄ. By using a genera
The cores of extended affine Lie algebras of reduced types were classified except for type A 1 . In this paper we determine the coordinate algebra of extended affine Lie algebras of type A 1 . It turns out that such an algebra is a unital n -graded Jordan algebra of a certain type, called a Jordan t
We study, in the path realization, crystals for Demazure modules of affine Lie algebras of types A Ž1. , B Ž1. , C Ž1. , D Ž1. , A Ž2. , A Ž2. , and D Ž2. . We find a special sequence of affine Weyl group elements for the selected perfect crystal, and show that if the highest weight is l⌳ , the Dem
The theory of Vogan diagrams, which are Dynkin diagrams with an overlay of certain additional information, allows one to give a rapid classification of finitedimensional real semisimple Lie algebras and to make use of this classification in practice. This paper develops a corresponding theory of Vog
