Abstract: Conformal Field Theories (CFTs) have many more symmetries in two dimensions than in higher dimensions.

The question I want to discuss is: Are rational CFTs dense in the moduli space of such manifolds? Although I won't be able to answer this question, I will describe how conformal perturbation theory can be used to address it. To this end I will present a toy computation for the K3 manifold.
