Truncated Modules and Linear Presentations of Vector Bundles
International mathematics research notices
We give a new method to construct linear spaces of matrices of constant rank, based on truncated graded cohomology modules of certain vector bundles as well as on the existence of graded Artinian modules with pure resolutions. Our method allows one to produce several new examples, and provides an alternative point of view on the existing ones. 2010 Mathematics Subject Classification. 13D02, 16W50, 15A30, 14J60.doi:10.1093/imrn/rnx032 fatcat:uaaojndrsrc5hoif5ufebvsyoq
