【 摘 要 】

We study the structure of the 0-Schur algebra S-0(n,r) following the geometric construction of S-0 (n, r) by Jensen and Su [12]. The main results are the construction and classification of indecomposable projective modules. In addition, we construct bases of these modules and their homomorphism spaces. We also give a filtration of projective modules, which leads to a decomposition of S-0(n, r) into indecomposable left modules. (C) 2016 Elsevier Inc. All rights reserved.
