722. Generalized bicircular projections via rank preserving maps on the spaces of symmetric and antisymmetric operatorsAjda Fošner, Dijana Ilišević, 2011, original scientific article Abstract: V članku so obravnavane naslednje, med seboj povezane, preslikave na simetričnih in antisimetričnih operatorjih, ki delujejo na kompleksnem Hilbertovem prostoru: linearni ohranjevalci ranga ena na simetričnih operatorjih, linearni ohranjevalci ranga dva na antisimetričnih operatorjih, surjektivne linearne izometrije in posplošeni bicirkularni projektorji.
Keywords: matematika, teorija operatorjev, posplošene bicirkularni projektorji, ohranjevalci ranga, simetrični operatorji, antisimetrični operatorji
