The conjectural integral surgery triangle for rationally null-homologous knots
The conjectural integral surgery triangle for rationally null-homologous knots
Let be a rationally null-homologous knot in , and let and be the slope data used in the construction. Given and sufficiently large , define the sutured instanton homology objects appearing in the surgery triangle. The integral surgery triangle conjecture. There exists an exact triangle
\xymatrix{ \boldsymbol{\gamma}_{2\hat{\lambda}-(2m+2k-1)\hat{\mu}}\ar[rr]^{\pi_{m,k}(\hat{\mu})}&&\widehat{\mathbf{\Gamma}}_{m-1+2k}\ar[dl]\\ &\widehat{\mathbf{Y}}_{\hat{\lambda}-m\hat{\mu}}=I^{\sharp}(-\widehat{Y}_{-m}(\widehat{K}))\ar[ul]& }Moreover, if is not the Seifert longitude , then
This is the proposed integral surgery formula in the rationally null-homologous setting; the source gives no evidence that it has been proved or refuted.
