DESCRIPTION:Speakers: Alessio Cela (Cambridge)\n\nIn this talk\, I will ex
 plain how the non-vanishing of fixed-domain curve counts (Tevelev degrees)
  in a fixed curve class implies the stability of the tangent bundle TX​ 
 with respect to that class. I will then apply this result to establish the
  vanishing of most Tevelev degrees for Hirzebruch surfaces and compute the
  remaining cases by relating them to the corresponding invariants of the p
 rojective line. I will also explain how fixed-domain curve counts can be u
 sed to determine the splitting type of the restriction of the tangent bund
 le of certain varieties along a general rational curve.\n\nhttps://indico.
