Derived categories of flips and cubic hypersurfaces

چکیده

A classical result of Bondal-Orlov states that a standard flip in birational geometry gives rise to fully faithful functor between derived categories coherent sheaves. We complete their embedding into semiorthogonal decomposition by describing the complement. As an application, we can lift "quadratic Fano correspondence" (due Galkin-Shinder) Grothendieck ring varieties smooth cubic hypersurface, its variety lines, and Hilbert square, decomposition. also show square hypersurface dimension at least 3 is again variety, so particular lines on visitor. The most interesting case fourfold, where this exhibits first higher-dimensional hyperk\"ahler as

Derived 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.

Unirationality of Cubic Hypersurfaces

A remarkable result of [Segre43] says that a smooth cubic surface over Q is unirational iff it has a rational point. [Manin72, II.2] observed that similar arguments work for higher dimensional cubic hypersurfaces satisfying a certain genericity assumption over any infinite field. [CT-S-SD87, 2.3.1] extended the result of Segre to any normal cubic hypersurface (other than cones) over a field of ...

Integral Points on Cubic Hypersurfaces

Let g ∈ Z[x1, . . . , xn] be an absolutely irreducible cubic polynomial whose homogeneous part is non-degenerate. The primary goal of this paper is to investigate the set of integer solutions to the equation g = 0. Specifically, we shall try to determine conditions on g under which we can show that there are infinitely many solutions. An obvious necessary condition for the existence of integer ...

Rational Curves on Smooth Cubic Hypersurfaces

We prove that the space of rational curves of a fixed degree on any smooth cubic hypersurface of dimension at least four is irreducible and of the expected dimension. Our methods also show that the space of rational curves of a fixed degree on a general hypersurface in Pn of degree 2d ≤ min(n+4, 2n−2) and dimension at least three is irreducible and of the expected dimension.
