Now if I have to decide between these two course, which one do you think will help my application and my physics career more?
MATH 481 Intro to Differential Geometry (Vector and Tensor Analysis)
The basic tools of differential geometry will be introduced at the undergraduate level, by focusing on examples. This is a good first course for those interested in, or curious about, modern differential geometry, and in applying differential geometric methods to other areas.
Manifolds: configuration spaces, differentiable manifolds, tangent spaces, tangent bundles, orientability.
Calculus on manifolds: Vector fields, flows, tensor fields.
Differential forms and exterior calculus.
Integration theory: Generalized Stokes theorem, de Rham cohomology.
Riemannian geometry: Riemannian metrics, geodesics.
