    Abstract

    Kähler manifolds have a natural hyperkähler structure associated with (part of) their cotangent bundles. Using projective superspace, we construct four-dimensional N= 2 models on the tangent bundles of some classical Hermitian symmetric spaces (specifically, the four regular series of irreducible compact symmetric Kähler manifolds, and their non-compact versions). A further dualization yields the Kähler potential for the hyperkähler metric on the cotangent bundle.
