Linial–Meshulam torsion-freeness conjecture for first homology
Linial–Meshulam torsion-freeness conjecture for first homology
Let denote the Linial–Meshulam random -dimensional simplicial complex, and let be the constant appearing in the homological phase transition. A sequence has bounded away from if there is a positive constant such that for all sufficiently large . Torsion-freeness conjecture. For every such , is torsion-free with high probability. The conjecture concerns the apparent absence of torsion in first homology away from the critical window around ; extensive experiments support it, but the statement is presented as unproved.
