Abstract: We discuss from a geometric point of view the connection between therenormalization group flow for non-linear sigma models and the Ricci flow.This offers new perspectives in providing a geometrical landscape for 2Dquantum field theories. In particular we argue that the structure of Ricci flowsingularities suggests a natural way for extending, beyond the weak couplingregime, the embedding of the Ricci flow into the renormalization group flow.
