Riemannian geometry explores curved spaces and their properties. You'll study manifolds, metrics, geodesics, and curvature tensors. The course covers how to measure distances and angles on curved surfaces, analyze the shape of space, and understand the geometry of our universe. You'll also dive into applications in physics, particularly general relativity.

Is Riemannian Geometry hard?

Riemannian geometry is pretty challenging, not gonna lie. It builds on concepts from multivariable calculus, linear algebra, and differential geometry, so you need a solid math foundation. The abstract nature of the subject can be mind-bending at first. But once you get the hang of it, it's super rewarding. Just be prepared to put in some serious work and don't be afraid to ask for help.
