Geometric components of representation spaces via robust families of submanifolds

Gabriele Viaggi

We introduce robust families of submanifolds for a linear Lie group $G$ . We show that they give rise to geometric subspaces of the representation space $Hom (Γ, G)$ . As an appl…

Small eigenvalues of random 3-manifolds

Ursula Hamenstaedt, Gabriele Viaggi

We show that for every $g \geq 2$ there exists a number $c (g) > 0$ such that the smallest positive eigenvalue of a random closed 3-manifold $M$ of Heegaard genus $g$ is at most $c(g)/…
