Abstract:We study symmetry properties of quaternionic Kähler manifolds obtained by the HK/QK correspondence. To any Lie algebra g of infinitesimal automorphisms of the initial hyper-Kähler data we associate a central extension of g, acting by infinitesimal automorphisms of the resulting quaternionic Kähler manifold. More specifically, we study the metrics obtained by the one-loop deformation of the c-map construction, proving that the Lie algebra of infinitesimal automorphisms of the initial projective special Kähler m… Show more
