The finite-cover topological overlap conjecture
The finite-cover topological overlap conjecture
Let be a connected -dimensional simplicial complex whose fundamental group has property T. The finite-cover topological overlap conjecture. There exists such that every finite cover of has the -topological overlap property. This is proposed as a consequence of higher-property-T methods together with integral and mod- expansion; the source gives no resolution status.
