Virtually nilpotent groups' profile equivalence conjecture
Virtually nilpotent groups' profile equivalence conjecture
Let be a finitely generated virtually nilpotent group, let be a finite generating set, and let , , , and denote its sofic, hyperlinear, linear sofic, and weakly sofic profiles. Let denote the full residual finiteness growth. The virtually nilpotent profile conjecture.
This is presented as an ambitious generalization of the corresponding examples for virtually abelian and Heisenberg groups. The weakly sofic part is framed as an open direction, and no resolution is supplied.
