Desingularization of branch points of minimal surfaces in ${\mathbb{R}}^4$ (II)

We desingularize a branch point $p$ of a minimal disk $F_0(\mathbb{D})$ in ${\mathbb{R}}^4$ through immersions $F_t$’s which have only transverse double points and are branched covers of the plane tangent to $F_0(\mathbb{D})$ at $p$. If $F_0$ is a topological embedding and thus defines a knot in a sphere/cylinder around the branch point, the data of the double points of the $F_t$’s give us a braid representation of this knot as a product of bands.
