Strengthening Kazhdan's Property $(T)$ by Bochner Methods

$\Out(F_n)$ and the spectral gap conjecture

David Fisher

For $n > 2$ , given $ϕ_{1}, ..., ϕ_{n}$ randomly chosen isometries of $S^{2}$ , it is well-known that the group $\G$ generated by $ϕ_{1}, ..., ϕ_{n}$ acts ergodically on $S^{2}$ . It is conjectured in…
