(1987) which stipulates that the wreath (lexicographic) product of two hamiltonian decomposable di- rected graphs is also hamiltonian decomposable. Specifically, we show that the wreath product of hamiltonian decomposable directed graph G, such that |V (G)| is even and |V (G)| ? 3, with a directed m-cycle such that m ? 4 or the complete symmetric directed graph on m vertices such that m ? 3, is hamiltonian decomposable. We also show the wreath product of a directed n-cycle, where n is even, with a directed m-cycle, where m ? {2, 3}, is not hamiltonian decomposable</dc:description><dc:description xml:lang="sl">Potrdimo več posebnih primerov domneve, ki se je prvič pojavila pri Alspachu et al. (1987) in določa, da je venčni (leksikografski) produkt dveh usmerjenih grafov, ki sta razčlenljiva na hamiltonske cikle, prav tako razčlenljiv na hamiltonske cikle. Natančneje, pokažemo, da je venčni produkt hamiltonsko razčlenljivega usmerjenega grafa G, za katerega velja, da je |V (G)| sodo in |V (G)| ? 4, z usmerjenim m-ciklom, kjer je m ? 4, ali s popolnim simetričnim usmerjenim grafom na m vozliščih, kjer je m ? 3, hamiltonsko razčlenljiv. Pokažemo tudi, da venčni produkt usmerjenega n-cikla, kjer je n sodo, z usmerjenim m-ciklom, kjer je m ? {2, 3}, ni hamiltonsko razčlenljiv</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-H78TRFKY"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-H78TRFKY" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-H78TRFKY/ad6daec0-72fb-467f-85c4-929d30c1e2f4/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-H78TRFKY/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-H78TRFKY" /></ore:Aggregation></rdf:RDF>
