Generators and relations for Schur algebras Stephen Doty and Anthony Giaquinto Abstract. We obtain a presentation of Schur algebras (and $q$-Schur alggebras) by generators and relations, one which is compatible with the usual presentation of the enveloping algebra (quantized enveloping algebra) corresponding to the Lie algebra $\mathfrak{gl}_n$ of $n\times n$ matrices. We also find several new bases of Schur algebras.
