The Ashtekar–Jacobson–Smolin–Mason–Newman equations are used to construct the hyperkahler metrics on four-dimensional manifolds. These equations are closely related to anti-self-dual Yang–Mills equations of the infinite-dimensional gauge Lie algebras of all volume-preserving vector fields. Several examples of hyperkahler metrics are presented through the reductions of anti-self-dual connections. For any gauge group anti-self-dual connections on hyperkahler manifolds are constructed using the solutions of both Nahm and Laplace equations.
