2 00 1 An intrinsic characterization of p - symmetric Heegaard splittings ∗

چکیده
We show that every p-fold strictly-cyclic branched covering of a b-bridge link in S 3 admits a p-symmetric Heegaard splitting of genus g = (b−1)(p−1). This gives a complete converse to a result of Birman and Hilden, and gives an intrinsic characterization of p-symmetric Hee-gaard splittings as p-fold strictly-cyclic branched coverings of links.

متن کاملScharlemann-Thompson untelescoping of Heegaard splittings is finer than Casson-Gordon’s
Let H1∪P H2 be a Heegaard splitting of a closed 3-manifoldM , i.e., Hi (i = 1, 2) is a handlebody in M such that H1 ∪H2 = M , H1 ∩H2 = ∂H1 = ∂H2 = P . In [13], M.Scharlemann, and A.Thompson had introduced a process for spreading H1 ∪P H2 into a “thinner” presentation. The idea was polished to show that if the original Heegaard splitting is irreducible, then we can spread it into a series (A1 ∪P...
متن کاملS ep 2 00 5 HEEGAARD SPLITTINGS , THE VIRTUALLY HAKEN CONJECTURE AND PROPERTY ( τ ) MARC LACKENBY
The behaviour of finite covers of 3-manifolds is a very important, but poorly understood, topic. There are three, increasingly strong, conjectures in the field that have remained open for over twenty years – the virtually Haken conjecture, the positive virtual b 1 conjecture and the virtually fibred conjecture. Any of these would have profound ramifications for 3-manifold theory. In this paper,...
