We call a graph ?$G$? uniformly dissociated if all maximal dissociation sets are of the same cardinality. Characterizations of uniformly dissociated graphs with small cardinalities of dissociation sets are proven; in particular, the graphs in which all maximal dissociation sets are of cardinality 2 are the complete graphs on at least two vertices from which possibly a matching is removed, while the graphs in which all maximal dissociation sets are of cardinality 3 are the complements of the ?$K_4$?-free geodetic graphs with diameter 2. A general construction by which any graph can be embedded as an induced subgraph of a uniformly dissociated graph is also presented. In the main result we characterize uniformly dissociated graphs with girth at least 7 to be either isomorphic to ?$C_7$?, or obtainable from an arbitrary graph ?$H$? with girth at least 7 by identifying each vertex of ?$H$? with a leaf of a copy of ?$P_3$?</dc:description><dc:description xml:lang="sl">Množica vozlišč ?$D$? grafa ?$G$? se imenuje disociacijska množica, če ima vsako vozlišče množice ?$D$? največ enega soseda iz ?$D?$. Pravimo, da je graf enakomerno disociiran, če imajo vse njegove maksimalne disociacijske množice isto moč. V članku dokažemo karakterizacije enakomerno disociiranih grafov z majhnimi močmi disociacijskih množic; tako so grafi, v katerih imajo vse maksimalne disociacijske množice dva elementa, natanko polni grafi na vsaj dveh vozliščih, iz katerih so lahko odstranjene tudi povezave kakega prirejanja, medtem ko so grafi, v katerih so vse maksimalne disociacijske množice moči 3, natanko komplementi geodetskih grafov z diametrom 2, ki nimajo induciranih podgrafov izomorfnik ?$K_4$?. Predstavimo tudi splošno konstrukcijo, s katero lahko poljuben graf vložimo kot induciran podgraf v nek enakomerno disociiran graf. Glavni rezultat je karakterizacija enakomerno disociiranih grafov, v katerih so vsi cikli dolžine vsaj 7, kot grafov, ki so bodisi izomorfni grafu ?$C_7$? ali pa jih lahko dobimo iz poljubnega grafa ?$H$?, v katerem so vsi cikli dolžine vsaj 7, tako da identificiramo vsako vozlišče grafa ?$H$? z listom kopije grafa ?$P_3$?</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-0COBRRGY"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-0COBRRGY" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-0COBRRGY/ed4583f3-8d7d-4a41-91df-d41c25683837/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-0COBRRGY/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-0COBRRGY" /></ore:Aggregation></rdf:RDF>
