Appears in collection : 2023 - T2 - WS1 - GAP XVIII: Homotopy algebras and higher structures
I will explain the construction of the Fukaya-Morse category of a Riemannian manifold X -- an A-infinity category where the higher composition maps are given in terms of numbers of embedded trees in X, with edges following the gradient trajectories of certain Morse functions. I will give simple examples and explain different approaches to understanding the structure and proving the quadratic relations on the structure maps -- (1) via homotopy transfer, (2) effective field theory (“second quantization”) approach, (3) topological quantum mechanics (“first quantization”) approach. The talk is based on a joint work with O. Chekeres, A. Losev and D. Youmans, arXiv:2112.12756.
