Generalized Knot Groups: A Survey of Extensions and Missing Categorical Links — E8 Intelligence Research

FINDING: The search results are a mix of lecture videos and one abstract on generalized knot groups; no direct Aganagic-derived-category/Lagrangian-torus-fibration/Ext-group paper appears. The only concrete mathematical content is the generalized knot group extension series \(G_n(K)\). | MATH: Classical knot group \(G_1(K) = \pi_1(S^3 \setminus K)\). Wada–Kelly generalization: \(G_n(K)\) with \(G_1(K) \hookrightarrow G_n(K)\) (inclusion as subgroup). No explicit presentation, no Ext groups, no derived category data given. | CONNECTION: None explicit. Generalized knot groups relate to covering spaces (lattice of finite-index subgroups), but no golden ratio, base-60, or crystallographic symmetry appears in the abstract. The torus appears only as a surface in a topology lecture, not as a Lagrangian fibration. | DEPTH: 2 — the abstract is a known algebraic topology result (group extensions of knot groups), but the search failed to retrieve the Aganagic invariant material.
