Cayley Form

Definition

The Cayley form is a specific way to represent the connections of a Riemannian manifold, particularly focusing on how vectors are related to curvature and holonomy. It provides insight into how vectors change as they are parallel transported around loops in the manifold, which is essential in understanding the geometric structure and properties of spaces with curvature.
