Doan, Aleksander; Walpuski, Thomas On counting associative submanifolds and Seiberg-Witten monopoles. (English) Zbl 1436.53035 Pure Appl. Math. Q. 15, No. 4, 1047-1133 (2019). Summary: Building on ideas from [Zbl 0926.58003; Zbl 1256.53038; Zbl 1391.53029; A. Heydys, “\(G_2\) instantons and the Seiberg-Witten monopoles”, Preprint, arXiv:1703.06329], we outline a proposal for constructing Floer homology groups associated with a \(G_2\)-manifold. These groups are generated by associative submanifolds and solutions of the ADHM Seiberg-Witten equations. The construction is motivated by the analysis of various transitions which can change the number of associative submanifolds. We discuss the relation of our proposal to Pandharipande and Thomas’ stable pair invariant of Calabi-Yau 3-folds.
