Mar 8, 2019 at 18:38 | comment | added | Vincent L. | Hi Alec! I mean, existence would already be good news but in the end I'm interested in knowing about some structure being preserved by functors between different instances of the Fukaya category and I dont think I would be able to SEE that from just knowing the natural transformation exists | |
Mar 8, 2019 at 18:06 | comment | added | Alec Rhea | Interesting question and welcome to MO Vincent — out of curiosity, what would an explicit construction give you that existence wouldn’t (aside from the obvious advantage of a better understanding of the machinery in play, but in the context of proving something further is there an advantage)? | |
