= Bel decomposition
{wiki=Bel_decomposition}
Bel decomposition, also known as Bel's Theorem or the Bel decomposition theorem, is a concept from differential geometry and mathematical physics, particularly in the context of general relativity. It refers to a specific way of decomposing the curvature of a spacetime into different contributions, allowing a clearer understanding of the gravitational field. In general relativity, the curvature of spacetime is described by the Riemann curvature tensor, which encodes information about the curvature caused by mass and energy distributions.
