Factorial Nodal Threefolds in P 5
In this paper we study a 3-fold X ⊂ P that is a complete intersection of two hypersurfaces Fn and Gk of degree n and k respectively such that n ≥ k and the only singularities of X are ordinary double points. The 3-fold X is called factorial if every surface in X is cut by a hypersurface in P. The factoriality of the 3-fold X is equivalent to a global topological condition rkH4(X,Z) = 1, which f...
متن کاملQ-factorial Quartic Threefolds
We prove that a nodal quartic threefold X containing no planes is Q-factorial provided that it has not more than 12 singular points, with the exception of a quartic with exactly 12 sin-gularities containing a quadric surface. We give some geometrical constructions related to the latter quartic.
متن کاملRigid curves in complete intersection Calabi-Yau threefolds
Working over the complex numbers, we study curves lying in a complete intersection K3 surface contained in a (nodal) complete intersection Calabi-Yau threefold. Under certain generality assumptions, we show that the linear system of curves in the surface is a connected componend of the the Hilbert scheme of the threefold. In the case of genus one, we deduce the existence of infinitesimally rigi...
متن کاملNonrational Nodal Quartic Threefolds
The Q-factoriality of a nodal quartic 3-fold implies its non-rationality. We prove that a nodal quartic 3-fold with at most 8 nodes is Q-factorial, and we show that a nodal quartic 3-fold with 9 nodes is not Q-factorial if and only if it contains a plane. However, there are non-rational non-Q-factorial nodal quartic 3-folds in P. In particular, we prove the non-rationality of a general non-Q-fa...
متن کاملAcm Vector Bundles on Prime Fano Threefolds and Complete Intersection Calabi Yau Threefolds
In this paper we derive a list of all the possible indecomposable normalized rank–two vector bundles without intermediate cohomology on the prime Fano threefolds and on the complete intersection Calabi-Yau threefolds, say V , of Picard number ρ = 1. For any such bundle E, if it exists, we find the projective invariants of the curves C ⊂ V which are the zero–locus of general global sections of E...
