摘要：When X = X-n is a blowup of P-2 at n points x1, ... , x(n) with n <= 9, there is a canonical (affine) Lie algebra bundle epsilon(En)(0) over it, where E-9 is the affine E-8. In this paper, we will give a detail study of the relationship between the geometry of X, and the deformability of epsilon(En)(0).
