Schur functions were first studied by Cauchy in 1815, although they were named after Schur, who in 1901 showed that they were isomorphic to an irreducible character of a symmetric group under the Frobenius character map. Since then they have arisen in a variety of areas including algebraic geometry where Schur functions agree with Schubert classes in the cohomology ring of the complex Grassmannian, and quantum mechanics where they are related to quantum states.

Schur 函数最初由 Cauchy 于 1815 年研究，尽管它们是以 Schur 的名字命名的，Schur 于 1901 年证明它们同构于 Frobenius 特征映射下对称群的不可约特征。从那时起，它们出现在各个领域，包括代数几何（舒尔函数与复格拉斯曼上同调环中的舒伯特类一致）以及量子力学（它们与量子态相关）。
