WebOften conformal metrics are treated by selecting a metric in the conformal class, and applying only "conformally invariant" constructions to the chosen metric. A conformal metric is conformally flat if there is a metric representing it that is flat, in the usual sense that the Riemann curvature tensor vanishes. It may only be possible to find a ...

WebMay 28, 2024 · This workshop will survey some recent progress in understanding methods for constructing, analyzing, and classifying Ricci-flat metrics, Ricci solitons, and various flows. These methods include traditional geometric estimate-based methods as well as numerical approaches to approximating Ricci-flat metrics. WebFlat space and Euclidean space have more or less the same meaning. They usually indicate Minkowski spacetime (i.e. a spacetime isometrically isomorphic to R n equipped with the standard Minkowsky metric η a b) or R n equipped with the standard Euclidean metric δ … WebMar 12, 2024 · Therefore, it is easy to see that a locally conformally flat metric or Einstein metric must be Bach-flat. But the converse is not true in general. In this note, we study the critical metrics of \(\mathcal {F}_\tau \) under the Bach-flat condition and prove the following results. Theorem 1.1.
