“Serre’s Conjecture” refers to a statement made by J.-P. Serre in 1955 regarding whether finitely generated projective modules are free over a polynomial ring k[x1, ..., xn], where k is a field. This question arose from the analogy with affine schemes, where the affine n-space over k is contractible, leading to only trivial bundles. The inquiry was whether a similar result held in algebraic geometry. In this context, algebraic vector bundles over Spec k[x1, ..., xn] correspond to finitely generated projective modules over k[x1, ..., xn], making the question equivalent to determining if such projective modules are free for any base field k. Serre framed his statement as an open problem within the emerging sheaf-theoretic framework of algebraic geometry in the mid-1950s. He did not speculate on the outcome in his published work. However, a presumed positive answer to his question quickly became known as “Serre’s Conjecture.” Interest in this conjecture grew further with the development of two related fields: homological algebra and algebraic K-theory.
