Abstract
We construct a new family of compact orbifolds O(4)(Theta) with a positive self dual Einstein metric and a one-dimensional group of isometries. Together with another family, introduced in Boyer et al. (2002) [7] and here denoted by O(4)(Omega), these examples classify all 4-dimensional orbifolds that are quaternion Kahler quotients by a torus of real Grassmannians. (C) 2009 Elsevier B.V.
