Séminaires : Géométrie énumérative

Our goal is to count curves satisfying certain conditions. Gromov--Witten theorists have reduced this question to certain calculations in cohomology or Chow groups. When you perform the "same" calculations in K theory, you get different numbers! Called ``quantum K invariants,'' they admit a physics interpretation just like the usual curve counts. We present a basic toolkit before discussing connections with log geometry and surveying open, doable questions.
