$Z_{n}$ -manifolds in 4-dimensional graph-manifolds

Alexandra Mozgova

A standard fact about two incompressible surfaces in an irreducible 3-manifold is that one can move one of them by isotopy so that their intersection becomes $π_{1}$ -injective. By ex…

The toric cobordisms

Alexandra Mozgova

A smooth closed 3-manifold $M$ fibered by tori $T^{2}$ is characterized by an element $ϕ \in G L (2, Z)$ . We show that $M$ is the boundary of a 4-manifold fibered by tori over a…
