Abstract:
For any n a (c) 3/4 3, let R(n) denote the root category of finite-dimensional nilpotent representations of cyclic quiver with n vertices. In the present paper, we prove that R(n - 1) is triangle-equivalent to the subcategory of fixed points of certain left (or right) mutation in R(n). As an application, it is shown that the affine Kac-Moody algebra of type A integral (n-2) is isomorphic to a Lie subalgebra of the Kac-Moody algebra of type A integral (n-1).
