The strong NE-equivalence conjecture for simple homotopy types

About 21 years old · traced to

Let {Xi}i=1∞\{X_i\}_{i=1}^\infty be a family of finite simplicial complexes. The strong NE-equivalence conjecture. There exists an infinite family of finite simplicial complexes {Xi}i=1∞\{X_i\}_{i=1}^\infty, which all have the same simple homotopy type, such that

Xi̸≃NEXjX_i\not\simeq_{\text{\tt NE}} X_j

for all i≠ji\neq j. This strengthens the weak conjecture by requiring infinitely many pairwise non-NE-equivalent complexes within a single simple homotopy type; its status is left open in the supplied text.
