We consider the recently constructed heterotic-type lower-dimensional superstrings. Using a theorem of Arbarello and Cornalba about the family of line bundles on compactified moduli space, we prove that these models have a vanishing cosmological constant.

We consider the recently constructed heterotic-type lower-dimensional superstrings. Using a theorem of Arbarello and Cornalba about the family of line bundles on compactified moduli space, we prove that these models have a vanishing cosmological constant.File in questo prodotto:
