Abstract
CFTs are naturally defined on Riemann surfaces. The rational ones can be solved using methods from algebraic geometry. One particular feature is the covariance of the partition function under the mapping class group. In genus , this yields modular forms, which can be linked to ordinary differential equations of hypergeometric type with algebraic solutions.
