The mod-p^r hyperbolicity amplification of Moore's conjecture
The mod-p^r hyperbolicity amplification of Moore's conjecture
Let be a prime and a positive integer. A -local space is mod- hyperbolic when the number of -summands in grows exponentially, namely
The mod- hyperbolicity conjecture. Let be a finite simply-connected -complex. If is rationally hyperbolic, then it is mod- hyperbolic for all primes and positive integers . The conjecture strengthens Moore's conjecture by requiring exponential growth of every prescribed torsion order, rather than merely torsion of arbitrarily high order. The paper's preceding results establish this behavior for certain spaces and, after excluding finitely many primes, in a broad family, but the stated universal claim remains open.
