Surgery-limit invariants for HP\mathit{HP} and HP#\mathit{HP}_{\#}

From papers

Let KS3K\subset S^3 be a knot, let pp be fixed, and let Sp/q3(K)S^3_{p/q}(K) denote p/qp/q surgery, with qq tending to infinity through integers relatively prime to pp. For each degree nn, consider the normalized ranks of the two Floer theories HP\mathit{HP} and HP#\mathit{HP}_{\#}. Surgery-limit invariant conjecture. The quantities

limq1qrk(HPn(Sp/q3(K)))\lim\limits_{q\to\infty} \frac{1}{q}\operatorname{rk}(\mathit{HP}^n(S^3_{p/q}(K)))

and

limq1qrk(HP#n(Sp/q3(K)))\lim\limits_{q\to\infty} \frac{1}{q}\operatorname{rk}(\mathit{HP}_{\#}^n(S^3_{p/q}(K)))

are well-defined invariants of the knot KK. This is proposed as the analogue for HP\mathit{HP} and HP#\mathit{HP}_{\#} of the SL(2,C)\operatorname{SL}(2,\mathbb{C}) Casson knot invariant; the source does not provide a resolution.
