Torsion-freeness conjecture for homology of random simplicial complexes

About 10 years old · traced to

Let Yd(n,p)Y_d(n,p) be the random dd-dimensional simplicial complex, and let cd∗c_d^* be the real number such that p=cd∗/np=c_d^*/n is a one-sided sharp threshold for the non-triviality of Hd(Yd(n,p);R)H_d(Y_d(n,p);\mathbb R). For p=p(n)p=p(n), suppose that ∣np−cd∗∣|np-c_d^*| is bounded away from 00. Torsion-freeness conjecture. For every d≥2d\geq 2, the group Hd−1(Yd(n,p);Z)H_{d-1}(Y_d(n,p);\mathbb Z) is torsion-free asymptotically almost surely. The conjecture predicts that torsion does not appear in random simplicial complexes in this regime; the source does not give a resolution.
