Title  The nonrational limit of Dseries minimal models 
Abstract  We study the limit of Dseries minimal models when the central charge tends to an irrational value $c \leq 1$. We find that the limit theory's diagonal threepoint structure constant differs from that of Liouville theory by a distribution factor, which is given by a divergent Verlinde formula. Nevertheless, in the limit theory, correlation functions that involve both nondiagonal and diagonal fields are smooth functions of the fields' conformal dimensions. The limit theory is a nontrivial example of a nondiagonal, nonrational, solved twodimensional conformal field theory.
