The density of rational points on non-singular hypersurfaces, II

T. D. Browning, D. R. Heath-Brown

This paper establishes the conjecture that a non-singular projective hypersurface of dimension , which is not equal to a linear space, contains rational points of h…

The Kodaira dimension of spaces of rational curves on low degree hypersurfaces

Jason Starr

For a hypersurface in complex projective space $X\subset \PP^n$, we investigate the singularities and Kodaira dimension of the Kontsevich moduli spaces $\Kbm{0,0}{X,e}$ parametrizi…

Rational connectivity and sections of families over curves

T. Graber, J. Harris, B. Mazur +1

We show that if a family of complex varieties over a base B admits a section when restricted to a very general curve in B, then the family must contain a subfamily of rationally co…

Rational curves on hypersurfaces of low degree, II

Joe Harris, Jason Starr

This is a continuation of "Rational curves on hypersurfaces of low degree", math.AG/0203088. We prove that if d^2+d+1 < n and d > 2, then for a general hypersurface X_d in P^n of d…

A note on Hurwitz schemes of covers of a positive genus curve

Tom Graber, Joe Harris, Jason Starr

We prove the irreducibility of the space parametrizing branched covers of a fixed Riemann surface of degree , with at least 2d branch points, and with monodromy group equal…

Abel-Jacobi maps associated to smooth cubic threefolds

Joe Harris, Mike Roth, Jason Starr

We pose some questions about spaces parametrizing rational curves on rationally connected varieties. We give a partial answer for cubic threefolds. Many of our results were previou…
