DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LNTS/61/">We
 ak approximation for del Pezzo surfaces of low degree</a>\nby Sam Streeter
  as part of London number theory seminar\n\n\nAbstract\nConjecturally\, th
 e rational points of a del Pezzo surface over a number field are well-dist
 ributed among the local points over all but finitely completions of the gr
 ound field—that is\, the surface satisfies weak weak approximation. Howe
 ver\, describing the rational points becomes harder as the degree of the d
 el Pezzo surface decreases. As such\, many questions remain unanswered for
  del Pezzo surfaces of low degree. In this talk\, I will report on recent 
 joint work with Julian Demeio\, in which we prove that del Pezzo surfaces 
 of degrees 1 and 2 satisfy weak weak approximation\, provided that we assu
 me some additional geometric structure in the form of conic fibrations.\n
