CFTs on Riemann Surfaces of genus $g \geq 1$ : Dependence on moduli

Marianne Leitner, Werner Nahm

The dependence of the Virasoro- $N$ -point function on the moduli of the Riemann surface is investigated. We propose an algebraic geometric approach that applies to any hyperelliptic…

Nahm's conjecture and coset models

Sinéad Keegan, Werner Nahm

When is a $q$ -series modular? This is an interesting open question in mathematics that has deep connections to conformal field theory. In this paper we define a particular $r$ -fold…
