Bookmark or Share- Relation between the Hessian matrix and curvatureThe idea is that this is the inverse of the "circle of best fit" to the graph. It describes how quickly the graph curves in $\mathbb{R}^2$. The Hessian describes "intrinsic" curvature. This type of curvature (to my understanding) is inherently two dimensional. In particular any one-manifold is always flat with respect to this notion of curvature.
- differential geometry - Intuitive definition for curvature ...This acceleration is directed towards the center of curvature of the curve. For instance, if you are travelling on a circular road, then you are constantly accelerating towards the center of the circle. The curvature $\kappa$ of a curve at a point is the magnitude of this acceleration when you are travelling at unit speed.
- differential geometry - What the curvature $2$-form really represents ...I mean, when we define curvature for curves on space, the curvature is meant to represent how much the curve deviates from a straight line. On the other hand, when reading books about General Relativity some time ago, I read that the curvature of the Levi-Civita connection is intended to encode the information of the difference between a ...
- Difference between second order derivative and curvature.The curvature is then defined as the inverse of the radius of curvature. So a large radius of curvature indicates a graph is nearly flat. This means the curvature, as the inverse of the radius of curvature, would be nearly zero for a line that is nearly straight. The more curled a graph is, the higher it's curvature value.
