Poincaré embedding multiple disjunction conjecture

Let NN and PP be Poincaré spaces, and let Q1,ots,QrQ_1,ots,Q_r be Poincaré spaces embedded in NN, with E(P,NQ)E(P,N-Q_\bullet) denoting the rr-cube of spaces of embeddings of PP into the complements NQSN-Q_S. Assume the homotopy codimension hypotheses and set

Σ=i=1r(nqi2).\Sigma=\sum_{i=1}^{r}(n-q_i-2).

Poincaré embedding multiple disjunction conjecture. If the handle codimension restrictions are omitted and r1r\geq1, then the rr-cube E(P,NQ)E(P,N-Q_\bullet) is (1p+Σ)(1-p+\Sigma)-cartesian. This extends the proven multiple-disjunction estimate for Poincaré embeddings beyond the handle-codimension range and predicts the corresponding connectivity of the total homotopy fiber.
