Abstrak

Three-dimensional string theories with 16 supersymmetries are believed to possess a non-perturbative U-duality symmetry SO(8,24, Z). By covariantizing the heterotic one-loop amplitude under U-duality, we propose an exact expression for the (∂φ) 4 amplitude, that reproduces known perturbative limits. The weak-coupling expansion in either of the heterotic, type II or type I descriptions exhibits the well-known instanton effects, plus new contributions peculiar to three-dimensional theories, including the Kaluza-Klein 5-brane, for which we extract the summation measure. This letter is a post-scriptum to hep-th/0001083.
