0,2 Heterotic Gauge Couplings and their M-Theory Origin
We work out the relation between automorphic forms on SO(2+s,2,Z) and gauge one-loop corrections of heterotic K3 x T^2 string compactifications for the cases s=0,1. We find that one-loop gauge corrections of any orbifold limit of K3 with arbitrary choice of gauge bundles can always be expressed by t...
