A NOTE ON THE ROOT SPACES OF AFFINE LIE ALGEBRAS OF TYPE $D_{\iota}^{(1)}$
초록
Let g = g(A) = (equation omitted) + be a symmetrizable Kac-Moody Lie algebra of type D/sub l//sup (1) with W as its Weyl group. We construct a sequence of root spaces with certain conditions. We also find the number of terms of this sequence is less then or equal to the hight of θ, the highest root.
