Many concepts such as division algebras, splitting fields or quadratic extensions appear here in a concrete and elementary context. Another important notion we shall introduce is that of the conic associated with quaternion algebra. In the end, we mention a classic theorem from 1930 called Witt’s theorem asserting that the associated conic determines a quaternion algebra up to isomorphism</dc:description><dc:description xml:lang="sl">V članku so predstavljene kvaternionske algebre. Številni koncepti, kot so algebre z deljenjem, razcepna polja in kvadratne razširitve, se v članku pojavijo v konkretnem in elementarnem kontekstu. Drug pomemben koncept, ki ga predstavimo, je stožnica, povezana s kvaternionsko algebro. Članek zaključimo s klasičnim izrekom iz tridesetih let 20. stoletja, imenovanim Wittov izrek, ki pravi, da pridružena stožnica definira kvaternionsko algebro do izomorfizma natančno</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-FMU9NJJ5"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-FMU9NJJ5" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-FMU9NJJ5/805eb954-ffd230-c-f93a6c61e74346c15-/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:dataProvider xml:lang="en">National and University Library of Slovenia</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-FMU9NJJ5/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-FMU9NJJ5" /></ore:Aggregation></rdf:RDF>
