Vanishing of the Vacuum Amplitude of Heterotic String Compactified on a Tensor Product of N=2 Superconformal Models.

摘要

The vacuum amplitude of heterotic string compactified on a tensor product of nine copies of c=1, N=2 superconformal models is shown to vanish due to a generalized Riemann's theta identity associated with the 12x12 matrix identity /sup t/BB=6/sup 2/I/sub 12/, identity B/sub ij/=-5(i=j), 1(inot =j).
