Abstract
We construct modular invariants in non-minimal conformal theories of central charge c < 1. We show these can also be considered as partition functions of c = 1 theories, and describe a free field with defect lines on a torus. This is applied to the determination of partition functions for critical Q-state Potts and O(n) models, with a special emphasis on the polymer (n = 0) case.
