Abstract: I'll talk about some of the algebro-geometric structures arising on spaces of meromorphic loops and how these can be used to build novel invariants of, for example, Poisson varieties or Landau-Ginzburg models. Informally, this is part of a program, largely unrealised, to attach elliptic cohomological invariants to noncommutative spaces.
