Abstract

In this paper, we consider a surface with only singularities of type $A$ whose smoothing is a $\mathbb{P}^2$ blown up at $8$ (resp. $9$) points. we use lines on such smooth surface to construct all the quasi-minuscule (resp. level one fundamental) representation bundles of $E_n$ (resp. affine $E_n$) over them. We also consider the vertex operator algebra structures on these bundles.

Keywords
