Necessarily, ?$N=\mathrm{lcm}(N_1, N_2, \dots, N_t)$? is a divisor of ?$2w + 1$? and ?$w=\sum^t_{i=1} \alpha_i$?. For ?$t=1$? we have the classic Oberwolfach problem. For ?$t=2$? this is the well-studied Hamilton-Waterloo problem, whereas for ?$t \ge 3$? very little is known. In this paper, we show, among other things, that the above necessary conditions are sufficient whenever ?$2w + 1 \ge (t + 1)N$?, ?$\alpha_i &gt; 1$? for every ?$i \in \{1, 2, \dots, t\}$?, and ?$\mathrm{gcd} (N_1, N_2, \dots, N_t) &gt; 1$?. We also provide sufficient conditions for the solvability of the generalized Oberwolfach problem over an arbitrary graph and, in particular, the complete equipartite graph</dc:description><dc:description xml:lang="sl">Pri posplošenem oberwolfaškem problemu ?$\rm{OP}_t(2w + 1; N_1, N_2, \dots , Nt; \alpha_1, \alpha_2, \dots, \alpha_t)$? iščemo faktorizacijo grafa ?$K_{2w + 1}$? na ?$\alpha_i C_{N_i}$?-faktorjev (kjer je ?$C_{N_i}$?-faktor grafa ?$K_{2w + 1}$? vpeti podgraf, katerega komponente so cikli dolžine ?$N_i \ge 3$?) za ?$i=1, 2, \dots , t$?. Potrebni pogoj za rešitev je, da je ?$N=\mathrm{lcm}(N_1, N_2, \dots, N_t)$? delitelj števila ?$2w + 1$? in da je ?$ w=\sum^t_{i=1} \alpha_i$?. Za ?$t=1$? imamo klasični oberwolfaški problem. Za ?$t=2$? je to dobro raziskani hamilton-waterloojski problem, medtem ko je za ?$t \ge 3$? znanega zelo malo. V tem članku med drugim pokažemo, da je zgornji potrebni pogoj tudi zadosten, kadarkoli je ?$2w + 1 \ge (t + 1)N$?, $?\alpha_i &gt; 1$? za vsak ?$i \in \{1, 2, \dots, t\}$?, in ?$\mathrm{gcd} (N_1, N_2, \dots, N_t) &gt; 1$?. Podamo tudi zadostne pogoje za rešljivost posplošenega oberwolfaškega problema nad poljubnim grafom in, še posebej, polnim ekvipartitnim grafom</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-RKIM2139"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-RKIM2139" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-RKIM2139/180884a2-e201-4b2b-88e2-cd08bf33057e/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-RKIM2139/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-RKIM2139" /></ore:Aggregation></rdf:RDF>
