Compactness conjecture for ADHM1,k_{1,k} monopoles

From papers

Let MM be the underlying manifold, and let (εi,Ψi,ξi,Ai)(\varepsilon_i,\Psi_i,{\bm\xi}_i,A_i) be a sequence of solutions of the blown-up ADHM1,k_{1,k} Seiberg--Witten equation satisfying

\slashedDAiΨi=0,\slashedDAi,Cξi=0,εi2ϖFAi=μ(Ψi)+μ(ξi),(Ψi,ξi)L2=1,\slashed D_{A_i}\Psi_i=0,\qquad \slashed D_{A_i,C}{\bm\xi}_i=0,\qquad \varepsilon_i^2\varpi F_{A_i}=\mu(\Psi_i)+\mu({\bm\xi}_i),\qquad \lVert(\Psi_i,{\bm\xi}_i)\rVert_{L^2}=1,

with εi0\varepsilon_i\to0. Compactness conjecture for ADHM1,k_{1,k} monopoles. After passing to a subsequence, there are a closed subset ZMZ\subset M of Hausdorff dimension at most one and a limiting triple (0,ξ0,A0)(0,{\bm\xi}_0^\infty,A_0^\infty) such that, outside ZZ and up to gauge transformations, (Ψi,ξi,Ai)(\Psi_i,{\bm\xi}_i,A_i) converges to (0,ξ0,A0)(0,{\bm\xi}_0^\infty,A_0^\infty) and εi1(Ψi,ξiξ0)\varepsilon_i^{-1}(\Psi_i,{\bm\xi}_i-{\bm\xi}_0^\infty) converges to (Ψ1,ξ1)(\Psi_1^\infty,{\bm\xi}_1^\infty). The limiting triple solves the limiting ADHM1,k_{1,k} Seiberg--Witten equation. Moreover, the section induced by ξ0{\bm\xi}_0^\infty extends continuously across ZZ, and on the corresponding unbranched covers the components (Ψ~1,j,ξ~1,j,A0,j)(\tilde\Psi_{1,j},\tilde{\bm\xi}_{1,j},A_{0,j}) solve the ADHM1,kj_{1,k_j} Seiberg--Witten equations. This conjectural compactness statement would provide the analytic control needed for the ADHM monopole construction and its use in associative counts.
