Internal and external stabilization of exotic surfaces in 4-manifolds

Oliviero Malech

We show that many explicit examples of exotic pairs of surfaces in a smooth 4-manifold become smoothly isotopic after one external stabilization with $S^{2} \times S^{2}$ or $CP^2\#\ove…

The multiple fibration problem for Seifert 3-orbifolds

Oliviero Malech, Mattia Mecchia, Andrea Seppi

We conclude the multiple fibration problem for closed orientable Seifert three-orbifolds, namely the determination of all the inequivalent fibrations that such an orbifold may admi…

A recipe for exotic 2-links in closed 4-manifolds whose components are topological unknots

Valentina Bais, Younes Benyahia, Oliviero Malech +1

We describe a construction procedure of infinite sets of $2$ -links in closed simply connected 4-manifolds that are topologically isotopic, smoothly inequivalent and componentwise t…
