We construct an orientable ribbon surface $F subset B^4$, which is universal in the following sense: any orientable 4-manifold $M cong B^4 cup (1-handles) cup (2-handles)$ can be represented as a cover of $B^4$ branched over $F$.

Abstract
We construct an orientable ribbon surface $F subset B^4$, which is universal in the following sense: any orientable 4-manifold $M cong B^4 cup (1-handles) cup (2-handles)$ can be represented as a cover of $B^4$ branched over $F$.File in questo prodotto:
