**Title: **Local systems and finite group symmetry in Floer theory

**Abstract**: Given a covering of a Lagrangian submanifold with a finite deck transformation group G, each representation of G produces a local system on the Lagrangian. When there is a finite group symmetry on a symplectic manifold, we discuss the construction of its orbifold mirror associated with the family of objects formed by a Lagrangian coupled with various local systems obtained through this procedure.

**Title: **Calabi-Yau structures on Rabinowitz Fukaya categories

**Abstract**: In this talk, I will first introduce the notion of proper Calabi-Yau structure on an A_infinity(or a dg category) and then the notion of relative proper Calabi-Yau structure on an functor between two A_infinity categories(or dg categories). Then I will explain that the Rabinowitz Fukaya category carries a proper Calabi-Yau structure under certain degree-wise finite assumption. Furthermore, I will discuss if the natural functor from wrapped Fukaya category to Rabinowitz Fukaya category carries a relative proper Calabi-Yau structure.
