Revisiting Atiyah-Hitchin manifold in the generalized Legendre transform
Masato Arai, Kurando Baba, Radu A. Ionas
We revisit construction of the Atiyah-Hitchin manifold in the generalized Legendre transform approach. This is originally studied by Ivanov and Rocek and is subsequently investigat…
An analogue of the Gibbons-Hawking Ansatz for quaternionic Kähler spaces
Radu A. Ionas
We show that the geometry of -dimensional quaternionic Kähler spaces with a locally free -action admits a Gibbons-Hawking-like description based on the Galick…
Twisted hyperkähler symmetries and hyperholomorphic line bundles
Radu A. Ionas
In this paper we propose and investigate in full generality new notions of (continuous, non-isometric) symmetry on hyperkähler spaces. These can be grouped into two categories, cor…
Gravitational instantons of type and a generalization of the Gibbons-Hawking Ansatz
Radu A. Ionas
We describe a quaternionic-based Ansatz generalizing the Gibbons-Hawking Ansatz to a class of hyperkähler metrics with hidden symmetries. We then apply it to obtain explicit expres…
A note on conformal symmetry in projective superspace
Radu A. Ionas, Andrew Neitzke
We describe a sufficient condition for actions constructed in projective superspace to possess an SU(2) R-symmetry. We check directly that this condition implies that the correspon…
Quaternionic Kahler spaces with large toric symmetry
Radu A. Ionas
We consider a general 4n-dimensional quaternionic Kahler geometry with a free action of the torus T^(n+1). The toric action lifts onto the Swann bundle of the quaternionic Kahler s…
