Self-dual Solutions to Euclidean Gravity

  title={Self-dual Solutions to Euclidean Gravity},
  author={Tohru and Eguchi and Stanford},
Recent work on Euclidean self-dual gravitational fields is reviewed. We discuss various solutions to the Einstein equations and treat asymptotically locally Euclidean self-dual metrics in detail. These latter solutions have vanishing classical action and nontrivial topological invariants, and so may play a role in quantum gravity resembling that of the Yang-Mills instantons.
