**Title: *Rational curves on del Pezzo surfaces*

**
**Abstract: **In this talk, we explore the connection between the 
enumerative geometry of rational curves on del Pezzo surfaces over a 
field k and the arithmetic properties of k. In particular, we classify 
the number of k-rational lines and conic families that can occur on del 
Pezzo surfaces of degrees 3 through 9 in terms of the Galois theory of 
k, and we give partial results in degrees 1 and 2. Our results 
generalize well-known theorems in the setting of smooth cubic surfaces. 
This is joint work in progress with Stephen McKean, Sam Streeter and 
Harkaran Uppal.

*Date:1 November 2024*, *Friday*
*Time: 15:40 /(GMT+3)/*
