--- res: bibo_abstract: - We find a graph of genus 5 and its drawing on the orientable surface of genus 4 with every pair of independent edges crossing an even number of times. This shows that the strong Hanani–Tutte theorem cannot be extended to the orientable surface of genus 4. As a base step in the construction we use a counterexample to an extension of the unified Hanani–Tutte theorem on the torus.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Radoslav foaf_name: Fulek, Radoslav foaf_surname: Fulek foaf_workInfoHomepage: http://www.librecat.org/personId=39F3FFE4-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0001-8485-1774 - foaf_Person: foaf_givenName: Jan foaf_name: Kynčl, Jan foaf_surname: Kynčl bibo_doi: 10.1007/s00493-019-3905-7 bibo_issue: '6' bibo_volume: 39 dct_date: 2019^xs_gYear dct_identifier: - UT:000493267200003 dct_isPartOf: - http://id.crossref.org/issn/0209-9683 - http://id.crossref.org/issn/1439-6912 dct_language: eng dct_publisher: Springer Nature@ dct_title: Counterexample to an extension of the Hanani-Tutte theorem on the surface of genus 4@ ...
