Graphing conjecture for low-degree homotopy groups of long links
Graphing conjecture for low-degree homotopy groups of long links
Let , , and be integers with and . Let denote the space of long links with components of dimension in , let denote the corresponding space of long knots, and let and be the indicated braid classes. For each pair or triple of components, use graphing and joining as in the statement, and let be the -sphere. Graphing conjecture. A minimal generating set for
is given by the inclusions of a generator of ; the result of graphing and then joining two components of for every pair of components with ; the image under graphing of a minimal generating set of for every pair with ; and, if , the result of graphing for every triple with . This conjecture proposes an explicit description of generators in terms of knot inclusions, graphing, joining, and sphere homotopy classes; the torsion subgroup is the remaining issue in determining these groups.
