In particular, 4-edge connected 4-regular maps (which are related to the 3-flow conjecture by Tutte) are handled. Formulae of several types of rooted 4-edge-connected 4-regular maps on the projective plane are presented. Several known results on the number of 4-regular maps on the projective plane are also derived. Finally, using Darboux's method, a nice asymptotic formula for the numbers of this type of maps is given which implies that almost every (loopless) 4-regular map on the projective plane has a separating cycle</dc:description><dc:description xml:lang="sl">V članku raziskujemo ukoreninjene (skoraj-)4-regularne zemljevide na projektivni ravnini glede na njihovo korensko valenco, število povezav, število notranjih lic, število nekorenskih vozliščnih zank in število ločevalnih ciklov. Še posebej obravnavamo 4-povezavno povezane 4-regularne zemljevide (ki so povezani s Tutteovo domnevo o 3-toku). Predstavimo formule za več vrst ukoreninjenih 4-povezavno povezanih 4-regularnih zemljevidov na projektivni ravnini. Izpeljemo tudi več znanih rezultatov glede števila 4-regularnih zemljevidov na projektivni ravnini. Nazadnje dobimo, s pomočjo Darbouxjeve metode, za število te vrste zemljevidov lepo asimptotsko formulo, iz katere sledi, da ima skoraj vsak (brezzančni) 4-regularen zemljevid na projektivni ravnini ločevalni cikel</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-QLFV3MQ0"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-QLFV3MQ0" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-QLFV3MQ0/dfbd1b79-73d7-4729-a5bd-aedbbcc9d3ec/PDF" /><edm:rights rdf:resource="http://creativecommons.org/licenses/by/4.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza na Primorskem, Fakulteta za naravoslovje, matematiko in informacijske tehnologije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-QLFV3MQ0/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-QLFV3MQ0" /></ore:Aggregation></rdf:RDF>
