چکیده
We prove that the moduli stacks of marked and labelled Hodgespecial Gushel–Mukai fourfolds are isomorphic. As an application, we construct rational maps from stack Hodge-special discriminant d to space (twisted) degree-d polarized K3 surfaces. use these results a counting formula for number fourdimensional fibers Fourier–Mukai partners very general with associated surface, lower bound this in case twisted surface.

Cubic Fourfolds and Spaces of Rational Curves
For a general nonsingular cubic fourfold X ⊂ P5 and e ≥ 5 an odd integer, we show that the space Me parametrizing rational curves of degree e on X is non-uniruled. For e ≥ 6 an even integer, we prove that the generic fiber dimension of the maximally rationally connected fibration of Me is at most one, i.e. passing through a very general point of Me there is at most one rational curve. For e < 5...
متن کاملTwisted Cubics on Cubic Fourfolds
We construct a new twenty-dimensional family of projective eight-dimensional holomorphically symplectic manifolds: the compactified moduli space M3(Y ) of twisted cubics on a smooth cubic fourfold Y that does not contain a plane is shown to be smooth and to admit a contraction M3(Y ) → Z(Y ) to a projective eight-dimensional symplectic manifold Z(Y ). The construction is based on results on lin...
متن کاملDerived Categories of Cubic Fourfolds
We discuss the structure of the derived category of coherent sheaves on cubic fourfolds of three types: Pfaffian cubics, cubics containing a plane and singular cubics, and discuss its relation to the rationality of these cubics.
متن کاملLagrangian subvarieties of abelian fourfolds
Let (W, ω) be a smooth projective algebraic variety of dimension 2n over C together with a holomorphic (2, 0)-form of maximal rank 2n. A subvariety X ⊂ W is called weakly lagrangian if dim X ≤ n and if the restriction of ω to X is trivial (notice that X can be singular). An n-dimensional subvariety X ⊂ W with this property is called lagrangian. For example, any curve C contained in a K3 or abel...
متن کاملModular Curves, Modular Surfaces, and Modular Fourfolds
We begin with some general remarks. Let X be a smooth projective variety of dimension n over a field k. For any positive integer p < n, it is of interest to understand, modulo a natural equivalence, the algebraic cycles Y = ∑ j mjYj lying on X, with each Yj closed and irreducible of codimension p, together with codimension p + 1 algebraic cycles Zj = ∑ i rijZij lying on Yj , for all j. There is...
