Arrondo Esteban, EnriqueFania, Maria Lucia2023-06-202023-06-2020060129-167X10.1142/S0129167X06003436https://hdl.handle.net/20.500.14352/49830In this paper, we show that any smooth subvariety of codimension two in G(1,4) (the Grassmannian of lines of P-4) of degree at most 25 is subcanonical. Analogously, we prove that smooth subvarieties of codimension two in G(1,4) that are not of general type have degree <= 32 and we classify all of them. In both classifications, any subvariety in the final list is either a complete intersection or the zero locus of a section of a twist of the rank-two universal bundle on G(1,4).journal articlehttp://www.worldscinet.com/ijm/ijm.shtmlmetadata only access512.7Projective spacesmooth surfacesgeneral typeGrassmanniansP-4Geometria algebraica1201.01 Geometría Algebraica
