Rank gradients of infinite cyclic covers of 3-manifolds
Jason DeBlois, Stefan Friedl, Stefano Vidussi
Given a 3-manifold M with no spherical boundary components, and a primitive class ϕin H^1(M;Z), we show that the following are equivalent: (1) ϕis a fibered class, (2) the rank gra…
On the topology of Symplectic Calabi-Yau 4-manifolds
Stefan Friedl, Stefano Vidussi
Let M be a 4-manifold with residually finite fundamental group G having b_1(G) > 0. Assume that M carries a symplectic structure with trivial canonical class K = 0 in H^2(M). Using…
A vanishing theorem for twisted Alexander polynomials with applications to symplectic 4-manifolds
Stefan Friedl, Stefano Vidussi
In this paper we show that given any 3-manifold N and any non-fibered class in H^1(N;Z) there exists a representation such that the corresponding twisted Alexander polynomial is ze…
The Thurston norm and twisted Alexander polynomials
Stefan Friedl, Stefano Vidussi
Using recent results of Agol, Przytycki-Wise and Wise we show that twisted Alexander polynomials detect the Thurston norm of any irreducible 3-manifold which is not a closed graph…
Minimal genus in 4-manifolds with a free circle action
Stefan Friedl, Stefano Vidussi
Let N be a closed irreducible 3-manifold and assume N is not a graph manifold. We improve for all but finitely many S^1-bundles M over N the adjunction inequality for the minimal c…
