GJS conjecture on skein-module dimension and Abouzaid–Manolescu homology

Let MM be a closed 33-manifold. The skein module S(M)S(M) is a [?][?]-vector space, and HP#0(M)HP^0_\#(M) denotes the degree-zero part of Abouzaid–Manolescu homology HP#(M)HP_\#(M).

GJS conjecture.

dimQ(A)S(M)=dimCHP#0(M).\dim_{\mathbb{Q}(A)} S(M)=\dim_{\mathbb{C}} HP^0_\#(M).

The preceding finiteness theorem shows that the left-hand side is finite, but its computation and its interpretation remain difficult and open. The conjecture proposes that this dimension is governed by Abouzaid–Manolescu homology.
