Multiple disjunction conjecture for spaces of embeddings

About 18 years old · traced to

Let NN be a smooth compact nn-dimensional manifold and assume s≥2s\geq 2. For 1≤i≤s1\leq i\leq s, let (Qi,∂0Qi,∂1Qi)(Q_i,\partial_0Q_i,\partial_1Q_i) be a smooth compact manifold triad, with the manifolds ∂0Qi\partial_0Q_i disjointly embedded in ∂N\partial N. For S⊂s‾S\subset\underline s, let QS=∐i∈SQiQ_S=\coprod_{i\in S}Q_i and let E(QS,N)E(Q_S,N) be the space of embeddings fixed on ∂0QS=∐i∈S∂0Qi\partial_0Q_S=\coprod_{i\in S}\partial_0Q_i. Multiple disjunction conjecture. In this situation the ss-dimensional cubical diagram formed by the spaces {E(QS,N)}\{E(Q_S,N)\} is (3−n+∑i(n−qi−2))(3-n+\sum_i(n-q_i-2))-cartesian. This is presented as a different form of the preceding multiple-disjunction statement; the result belongs to the homotopy-theoretic study of spaces of embeddings, and its asserted connectivity is established in the range covered by the cited Goodwillie–Klein work.
