We use this notion to prove some extension of Evans-Griffith criterion to characterize direct sums of line bundles. We also give. in the line of previous results by Costa and Miro-Roig, a cohomological characterization of exterior and symmetric powers of the universal bundles of the Grassmannian.engjournal articlehttp://www.sciencedirect.com/science/article/pii/S0021869309006061restricted access514.7Castelnuovo-Mumford regularityCriterionQuadricsSpacesGeometria algebraica1201.01 Geometría Algebraica
