Geometrijske lastnosti operatorjev : disertacijaTurnšek, AleksejV geometriji normiranih prostorov sta zelo pomembna pojma ortogonalnosti in ekstremnih točk. V kompleksen normiran vektorski prostor ▫${\cal X}$▫ uvedemo pojem ortogonalnosti na naraven način kot ... posplošitev pojma ortogonalnosti na Hilbertovem prostoru. Rečemo, da je vektor ▫$x$▫ iz ▫${\cal X}$▫ ortogonalen na vektor ▫$y$▫ iz ▫${\cal X}$▫, če velja ▫$\|x + \lambda y\| \ge \|x\|$▫ za vsako kompleksno število ▫$\lambda$▫. V prvem delu disertacije študiramo vprašanje ortogonalnosti jedra in zaloge vrednosti elementarnega operatorja na algebri omejenih operatorjev na Hilbertovem prostoru, glede na operatorsko normo in glede na von Neumann-Schattenove norme. V drugem delu disertacije definiramo matrične ekstremne točke, ki si posplošitev pojma kompleksnih ekstremnih točk. S pomočjo Parrottovega izreka uspemo karakterizirati tiste operatorske matrike, ki so matrične ekstremne točke enotske sfere v ▫$M_n({\cal B(H)})$▫. Z uporabo tega rezultata dokažemo operatorsko matrično različico Thorp-Whitleyjevega izreka.Type of material - dissertation ; adult, seriousPublication and manufacture - Ljubljana : [A.
