[Refined Floer theory for immersed Lagrangian surfaces]
Д. И. Тонконог |
|
Аннотация:
Holomorphic curves with boundary on an immersed Lagrangian surface can have
corners, due to which they may undergo a type of bubbling that does not
occur in the smooth case. I will explain an algebraic framework for
eliminating this problem, which results in well-defined Floer and open
Gromov-Witten theories. The main algebraic gadget is the higher genus
multiplicative preprojective algebra, which can be understood as the
singular fundamental group of an immersed surface. This is joint work with
Georgios Dimitroglou Rizell and Tobias Ekholm.
