The hyperkähler quotient is a concept from the field of differential geometry and mathematical physics, particularly in the study of hyperkähler manifolds and symplectic geometry. It generalizes the notion of a symplectic quotient (or Marsden-Weinstein quotient) to the context of hyperkähler manifolds, which possess a rich geometric structure.
