摘要：
We show that the bosonic sector of a (4, 0) supersymmetric sigma-model is a quasi Ricci-flat manifold with a closed torsion and vanishing scalar curvature; in the torsionless limit we recover the hyper-Kahler (4, 4) models. Using the harmonic superspace and the self-duality equations we derive the (4, 0) generalizations of the metrics of Taub-NUT and Eguchi-Hanson.
