Geometric Manin's Conjecture and rational curves

Algebraic Geometry 2019-04-17 v3

Abstract

Let XX be a smooth projective Fano variety over the complex numbers. We study the moduli spaces of rational curves on XX using the perspective of Manin's Conjecture. In particular, we bound the dimension and number of components of spaces of rational curves on XX. We propose a Geometric Manin's Conjecture predicting the growth rate of a counting function associated to the irreducible components of these moduli spaces.
