The torus-generator chain-map conjecture for convex toric domains
The torus-generator chain-map conjecture for convex toric domains
Let be a smooth convex toric domain with boundary . Let be the chain complex freely generated over by torus generators, with differential given by rounding a corner and locally losing one edge labeled . For a convex generator , let be the torus generator obtained by attaching to a vertical segment from to its upper-left endpoint and a horizontal segment from to its lower-right endpoint, labeling the new segments . The torus-generator chain-map conjecture. One can choose the contact form on specified in the perturbation lemma and a generic -compatible almost complex structure on such that the linear map
sending the admissible orbit set to the torus generator , is a chain map. This conjecture would give an improved version of the theorem for smooth convex toric domains by identifying the relevant ECH differential with the combinatorial torus-generator differential.
