Harmonic Analysis digs into Fourier series, transforms, and their applications. You'll explore periodic functions, orthogonal systems, and convergence theorems. The course covers signal processing, wavelets, and harmonic functions on groups. You'll also learn about Hilbert spaces, spectral theory, and how these concepts apply to physics and engineering problems.

Is Harmonic Analysis hard?

Harmonic Analysis can be pretty challenging. It's got a rep for being one of the tougher upper-level math courses. The concepts are abstract and require a solid grasp of linear algebra and real analysis. But don't let that scare you off. With consistent effort and practice, most students find it manageable. The key is to stay on top of the material and not fall behind.
