| Abstract: |
Part 1 (60 min) This is based on joint work with Masahito Yamazaki and Masahiro Futaki. In the first part, I will introduce a tropical coamoeba as a combinatorial object which encode the information of the Fukaya-Seidel category of the mirror of a toric Fano stack, and discuss its role in a torus-equivariant version of Kontsevich's homological mirror symmetry conjecture. Part 2 (90 min) In the second part, we discuss A-infinity categories associated with tropical coamoebas. In contrast to the first part where the main focus is on the symplectic side of the story, I plan to discuss the relation with the derived category of quiver representations in some detail. |
