Para-Kahler-Einstein structures on Walker 4-manifolds
(World Scientific Publishing Co Pte Ltd, 2016)A 4-dimensional Walker manifold (M-4, g, D) is a semi-Riemannian manifold (M-4, g) of signature (+ + --) (or neutral), which admits a field of null 2-plane. The goal of this paper is to study certain almost paracomplex ...
