Odvajanja na kolobarjih in operatorskih algebrah : diplomsko deloŠirovnik, NejcV prvem delu diplomskega dela se seznanimo s strukturama prakolobar in pol prakolobar. Na kolobarju vpeljemo pojme odvajanje, jordansko odvajanje in jordansko trojno odvajanje. I. N. Herstein je leta ... 1957 dokazal, da je na prakolobarju brez elementov reda dva vsako jordansko odvajanje tudi odvajanje. V diplomskem delu je predstavljen alternativni dokaz tega izreka, ki sta ga leta 1988 objavila M. Brešar in J. Vukman. J. Cusack je leta 1975 Hersteinov izrek posplošil na pol prakolobarje brez elementov reda dva. V diplomskem delu je predstavljen dokaz tega izreka, ki ga je leta 1988 objavil M. Brešar. M. Brešar je leta 1989 dokazal, da je vsako jordansko trojno odvajanje na pol prakolobarju brez elementov reda dva tudi odvajanje. V diplomskem delu najdemo dokaz tega izreka s krepkejšimi predpostavkami. Predstavljena sta tudi nova rezultata, ki spominjata na prej omenjen Brešarjev rezultat. Drugi del diplomskega dela sega na področje funkcionalne analize. Osnova je rezultat P. R. Chernoffa, ki govori o linearnih odvajanjih na standardnih operatorskih algebrah realnega ali kompleksnega Banachovega prostora. Predstavljene so različne posplošitve tega rezultata.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Maribor : [N.
