"Reeb vector fields
and open book decompositions"
by
Ko Honda
(USC)
Abstract:
According to a theorem of Giroux (and building on the work of
Thurston-Winkelnkemper),
there is a 1-1 correspondence between isotopy classes of contact
structures and equivalence classes
of open book decompositions. We give partial results towards
calculating the contact homology
of a contact structure (M, \xi) (in dimension 3) which is
supported by an open book with
pseudo-Anosov monodromy. This is joint work with Vincent Colin.
