Abstract

We consider Script C/Script ZN and Script C2/Script ZN orbifolds of heterotic string theories and Script ZN orbifolds of AdS3. We study theories with Script N = 2 worldsheet superconformal invariance and construct RG flows. Following Harvey, Kutasov, Martinec and Moore, we compute gcl and show that it decreases monotonically along RG flows- as conjectured by them. For the heterotic string theories, the gauge degrees of freedom do not contribute to the computation of gcl.
