The irreducibility of the spaces of rational curves on del Pezzo surfaces
نویسنده
چکیده
Let X be a del Pezzo surface of degree d, and assume that X is general if d = 1. We prove that the spaces M0,0 ( X, β ) are either empty or irreducible, if (d, β) 6= (1,−KX). When (d, β) = (1,−KX) it is well known that M0,0 ( X, β ) consists of twelve reduced points.

متن کاملWelschinger invariants of toric Del Pezzo surfaces with non-standard real structures
The Welschinger invariants of real rational algebraic surfaces are natural analogues of the Gromov-Witten invariants, and they estimate from below the number of real rational curves passing through prescribed configurations of points. We establish a tropical formula for the Welschinger invariants of four toric Del Pezzo surfaces, equipped with a non-standard real structure. Such a formula for r...
متن کاملOn the unirationality of del Pezzo surfaces of degree 2
Among geometrically rational surfaces, del Pezzo surfaces of degree 2 over a field k containing at least one point are arguably the simplest that are not known to be unirational over k. Looking for k-rational curves on these surfaces, we extend some earlier work of Manin on this subject. We then focus on the case where k is a finite field, where we show that all except possibly three explicit d...
متن کاملThe Nef Cone Volume of Generalized Del Pezzo Surfaces
We compute a naturally defined measure of the size of the nef cone of a Del Pezzo surface. The resulting number appears in a conjecture of Manin on the asymptotic behavior of the number of rational points of bounded height on the surface. The nef cone volume of a Del Pezzo surface Y with (−2)-curves defined over an algebraically closed field is equal to the nef cone volume of a smooth Del Pezzo...
متن کاملHigher Fano Manifolds and Rational Surfaces
Let X be a Fano manifold of pseudo-index ≥ 3 such that c1(X)− 2c2(X) is nef. Irreducibility of some spaces of rational curves on X implies a general point of X is contained in a rational surface.
