On the twistor spaces of ALE gravitational instantons of type
Nobuhiro Honda
We study the twistor spaces of toric ALE gravitational instantons of type and the associated non-standard minitwistor spaces introduced by Hitchin. By analyzing the base…

The Einstein-Weyl spaces associated to Segre quartic surfaces
Nobuhiro Honda, Fuminori Nakata
We find explicit examples of compact minitwistor spaces of genus one, whose Einstein-Weyl spaces have a connected component that is diffeomorphic to the de Sitter space. The induce…
