Lie Groups & Lie Algebras

Lie groups model continuous symmetries like rotations and rigid-body motions, combining algebra (group law) and calculus (smooth manifolds).

Curvature

Curvature measures how a geometric object bends, and it comes in several flavors: Gaussian, sectional, and Ricci curvature.

Geodesics & Exponential Map

Geodesics are the “straightest possible” paths on curved spaces (manifolds) and locally minimize distance.

Riemannian Metrics & Geometry

A Riemannian metric assigns an inner product to each tangent space, giving you a way to measure lengths and angles on curved spaces (manifolds).

Smooth Manifolds & Tangent Spaces

A smooth manifold is a space that looks like ordinary Euclidean space when you zoom in, glued together using charts that transition smoothly.
