Embedding-complex invariance conjecture for statistics of topological excitations

Let M1M_1 and M2M_2 be manifolds, and let Cp+1\mathcal{C}_{p+1} be the collection of all finite (p+1)(p+1)-dimensional simplicial complexes. Define

Cp+1(M)={CCp+1there is an embedding CM}.\mathcal{C}_{p+1}(M)=\{C\in\mathcal{C}_{p+1}\mid \text{there is an embedding }C\longrightarrow M\}.

For excitations of dimension at most pp, let Tp(M,G)T_p(M,G) denote the statistics group with fusion group GG.

Embedding-complex invariance conjecture. If

Cp+1(M1)=Cp+1(M2),\mathcal{C}_{p+1}(M_1)=\mathcal{C}_{p+1}(M_2),

then

Tp(M1,G)Tp(M2,G).T_p(M_1,G)\simeq T_p(M_2,G).

This proposes that statistics of excitations up to dimension pp are determined by which finite (p+1)(p+1)-dimensional complexes embed in the ambient manifold. The source presents this as a conjectural form of dimensional and global-topological dependence.
