Linearni ohranjevalci komutativnosti : magistrsko deloRadić, GordanaLinearni ohranjevalci komutativnosti na matrični algebri so tesno povezani s preslikavami, ki vse matrike ranga 1 preslikajo v matrike ranga 1. Zato najprej določimo obliko linearnih preslikav, ki ... ohranjajo rang 1, nato pa natančno opišemo ne singularne linearne preslikave na algebri kvadratnih matrik z elementi iz algebraično zaprtega polja F s karakteristiko 0. Z močnejšo predpostavko, da preslikava ohranja komutativnost v obe smeri, vendar sedaj brez predpostavke surjektivnosti, dobimo podoben rezultat. Linearne preslikave, ki ohranjajo komutativnost oziroma ohranjajo komutativnost v obe smeri, proučimo tudi na algebri zgoraj trikotnih matrik nad poljubnim poljem in na realni (jordanski) algebri hermitskih kompleksnih matrik. V slednjem primeru dobimo karakterizacijo celo brez predpostavke surjektivnosti in z ohranjanjem komutativnosti samo v eno smer.Type of material - master's thesis ; adult, seriousPublication and manufacture - Maribor : [G.
