Torsion and Open Book Decompositions
نویسنده
چکیده
We show that if (B, π) is an open book decomposition of a contact 3–manifold (Y, ξ), then the complement of the binding B has no Giroux torsion. We also prove the sutured Heegaard-Floer c-bar invariant of the binding of an open book is non-zero.

Addendum to: "Infinite-dimensional versions of the primary, cyclic and Jordan decompositions", by M. Radjabalipour
In his paper mentioned in the title, which appears in the same issue of this journal, Mehdi Radjabalipour derives the cyclic decomposition of an algebraic linear transformation. A more general structure theory for linear transformations appears in Irving Kaplansky's lovely 1954 book on infinite abelian groups. We present a translation of Kaplansky's results for abelian groups into the terminolo...
متن کاملRanks of modules relative to a torsion theory
Relative to a hereditary torsion theory $tau$ we introduce a dimension for a module $M$, called {em $tau$-rank of} $M$, which coincides with the reduced rank of $M$ whenever $tau$ is the Goldie torsion theory. It is shown that the $tau$-rank of $M$ is measured by the length of certain decompositions of the $tau$-injective hull of $M$. Moreover, some relations between the $tau$-rank of $M$ and c...
متن کاملComparing Open Book and Heegaard Decompositions of 3-manifolds
We study the maximal value of the Euler characteristic of the pages of all open book decompositions of closed orientable 3-manifolds. In particular, we describe some examples where the minimal genus Heegaard splittings of such 3-manifolds give rise to open book decompositions and other examples where the simplest open book decomposition has larger maximal Euler characteristic of pages than the ...
متن کاملPlanar Open Books and Floer Homology
Giroux has described a correspondence between open book decompositions on a 3–manifold and contact structures. In this paper we use Heegaard Floer homology to give restrictions on contact structures which correspond to open book decompositions with planar pages, generalizing a recent result of Etnyre.
متن کاملInvariants of Open Books of Links of Surface Singularities
Let M be an oriented 3-dimensional manifold. By a result of Giroux [6] there is a one-to-one correspondence between open book decompositions of M (up to stabilization) and contact structures on M (up to isotopy). In [5] Etnyre and Ozbagci consider three invariants associated with a fixed contact structure defined in terms of all open book decompositions supporting it: (1) the support genus, whi...
