Hyperkähler manifold
text:
In differential geometry, a hyperkähler manifold is a Riemannian manifold endowed with three integrable almost complex structures I , J , K that are Kähler with respect to the Riemannian metric g and satisfy the quaternionic relations I 2 = J 2 = K 2 = I J K = − 1 . In particular, it is a hypercomplex manifold. All hyperkähler manifolds are Ricci-flat and are thus Calabi–Yau manifolds. Hyperkähler manifolds were defined by Eugenio Calabi in 1979.
