摘要
This is our second paper in a series to study gravitational instantons, i.e. complete hyperkahler 4-manifolds with faster than quadratic curvature decay. We prove two main theorems: (i) The asymptotic rate of gravitational instantons to the standard models can be improved automatically. (ii) Any ALF-D-k gravitational instanton must be the Cherkis-Hitchin-Ivanov-Kapustin-Lindstrom-Rocek metric.
