--- res: bibo_abstract: - We give explicit formulas and algorithms for the computation of the Thurston–Bennequin invariant of a nullhomologous Legendrian knot on a page of a contact open book and on Heegaard surfaces in convex position. Furthermore, we extend the results to rationally nullhomologous knots in arbitrary 3-manifolds.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Sebastian foaf_name: Durst, Sebastian foaf_surname: Durst - foaf_Person: foaf_givenName: Marc foaf_name: Kegel, Marc foaf_surname: Kegel - foaf_Person: foaf_givenName: Mirko D foaf_name: Klukas, Mirko D foaf_surname: Klukas foaf_workInfoHomepage: http://www.librecat.org/personId=34927512-F248-11E8-B48F-1D18A9856A87 bibo_doi: 10.1007/s10474-016-0648-4 bibo_issue: '2' bibo_volume: 150 dct_date: 2016^xs_gYear dct_language: eng dct_publisher: Springer@ dct_title: Computing the Thurston–Bennequin invariant in open books@ ...
