For this purpose we use the geometrical interpretation of the splitting of the quotient bundle as well as the meaning of the number of the independent global sections of each of its summands.engCongruences on G(1,4) with split universal quotient bundlejournal articlehttp://www.sciencedirect.com/science/article/pii/S0393044005000999restricted access512.7Grassmann varietiesquotient bundlescongruencesGeometria algebraica1201.01 Geometría Algebraica
