On the geometry of four-dimensional Walker manifolds
We study the curvature properties of a large class of four-dimensional Walker metrics. Several interesting examples are found, in particular as regards local symmetry, conformal flatness and Einstein-like metrics. Studiamo le proprietà di curvatura di un’ampia classe di metriche di Walker di dimen...
