## Intermediate links of plane curves

with M. Borodzik

to appear in Isreal J. Math.

For a smooth complex curve we consider the link Lr obtained by intersecting the curve with a sphere of radius r. We prove that the diagram Dr obtained from Lr by a complex stereographic projection satisfies topological equalties. As a consequence we show that if Dr has no negative Seifert circles and Lr is strongly quasipositive and fibered, then the Yamada–Vogel algorithm applied to Dr yields a quasipositive braid.
