CRYSTALLIZED STRUCTURE FOR LEVEL 0 PART OF MODIFIED QUANTUM AFFINE ALGEBRA (U)OVER-TILDE(Q)((SL(2))OVER-CAP)

摘要

Crystal base of the level 0 part of the modified quantum affine algebra (U) over tilde(q)(<(sI(2))over cap>)(0) is given by path. Weyl group actions, extremal vectors and crystal structure of all irreducible components are described explicitly. [References: 11]
