Montesinos Amilibia, José MaríaMorton, Hugh R.2023-06-202023-06-2019910024-611510.1112/plms/s3-62.1.167https://hdl.handle.net/20.500.14352/58615It is proven that every fibred link in the 3-sphere S3 with k components can be obtained as the preimage of the braid axis for a d-sheeted simple branched cover over S3, branched along a suitable closed closed braid, with d=max{k,3}. More generally, it is shown that every open book decomposition of a closed oriented 3-manifold arises in a similar way. A major step in the proof involves showing that given a compact surface with boundary expressed as a d-fold simple branched covering of the 2-disk, d≥3, every homeomorphism of the surface fixing the boundary is isotopic to a lift of a homeomorphism of the disk. Finally, this perspective on fibred links is applied to interpret the conjecture, due to J. Harer, that all fibred links arise from the trivial knot by a sequence of so-called Hopf plumbings in terms of Markov moves on braids. This is a rather long, detailed, and readable paper that can be recommended as an introduction to many of the ideas discussed. The work actually dates from 1984.journal articlehttp://plms.oxfordjournals.org/content/s3-62/1/167.abstracthttp://www.oxfordjournals.org/metadata only access515.1simple d-sheeted cover of S 3 branched over a closed braidfibred linkmonodromyplumbing a Hopf bandMarkov move on the branch setTopología1210 Topología
