刻划了G(1,4)上没有中间上同调的向量丛。我们从泛丛的扩展和与它们相关的其他方面获得它们。特别地,我们从上同调得到了泛向量丛的一个刻画。
We characterize the vector bundles on G(1,4) that have no intermediate cohomology. We obtain them from extensions of the universal bundles and others related with them. In particular, we get a characterization of the universal vector bundles from their cohomology.
