Spectral Theory vs Perturbation Theory
Developers should learn spectral theory when working in fields like quantum computing, signal processing, or numerical analysis, as it underpins algorithms for eigenvalue problems, spectral methods in PDEs, and data analysis techniques such as spectral clustering meets developers should learn perturbation theory when working on simulations, modeling, or optimization problems in fields like computational physics, engineering, or machine learning, where exact solutions are intractable. Here's our take.
