摘要
We prove that a symmetric space is Osserman if its complexification is a complex hyper-Kahler symmetric space. This includes all pseudo-hyper-Kahler as well as para-hyper-Kahler symmetric spaces. We extend the classification of pseudo-hyper-Kahler symmetric spaces obtained by the first and the third author to the class of para-hyper-Kahler symmetric spaces. These manifolds are possible targets for the scalars of rigid N = 2 supersymmetric field theories with hypermultiplets on four-dimensional space-times with Euclidean signature. (C) 2004 Elsevier B.V.
