A graph ? is called k-integral if the extension degree of the splitting field of the characteristic polynomial of ? over rational field Q is equal to k. We prove that for any positive integers k and ?, the set of all finite connected graphs with algebraic degree at most k and maximum degree at most ? is finite. We study 2-integral Cayley graphs over finite groups G with respect to Cayley sets which are a union of conjugacy classes of G. Among other general results, we completely characterize all finite abelian groups having a connected 2-integral Cayley graph with valency 2, 3, 4 and 5. Furthermore, we classify the finite groups G that al Cayley graphs over G with bounded valency are 2-integral</dc:description><dc:description xml:lang="sl">V tem članku uvedemo pojem k-integralnih grafov. Graf ? imenujemo k-integralen, če je stopnja razširitve razcepnega polja karakterističnega polinoma grafa ? nad poljem racionalnih števil Q enaka k. Dokažemo, da je množica vseh končnih povezanih grafov z dano algebrajsko stopnjo in dano največjo stopnjo vozlišč končna. Grafi, ki so 1-integralni, so natanko integralni grafi, torej grafi, katerih vse lastne vrednosti so cela števila. Preučujemo 2-integralne Cayleyjeve grafe nad končnimi grupami G glede na Cayleyjeve množice, ki so unije konjugiranostnih razredov grupe G. Med drugim popolnoma okarakteriziramo vse končne abelove grupe, ki imajo povezan 2-integralen Cayleyjev graf valence 2, 3, 4 ali 5. Nadalje klasificiramo vse končne grupe G, za katere so vsi Cayleyjevi grafi nad G z omejeno valenco 2-integralni</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-UK4OP7M1"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-UK4OP7M1" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-UK4OP7M1/93ac95fc-4a26-4d7f-a73a-1c2b245b2730/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-UK4OP7M1/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-UK4OP7M1" /></ore:Aggregation></rdf:RDF>
