Partial fraction decomposition

This article discusses partial fraction decomposition from a mathematical perspective, moving beyond its typical use in integral calculus. It covers the theoretical foundations, including factorization of polynomials, the role of complex numbers via the Fundamental Theorem of Algebra, and generalization to principal ideal domains (PIDs). It also touches on applications to rational numbers and prime power denominators. The content is relevant to mathematics and computer science, particularly for those interested in algebraic structures and numerical methods.
