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

Secondary language

Abstract:We study several related maps from the space of symmetric (respectively, antisymmetric) operators, acting on a complex Hilbert space, to itself: rank preserving linear maps (more precisely, maps preserving rank one operators in the symmetric case, and maps preserving rank two operators in the antisymmetric case), surjective linear isometries and generalized bicircular projections.
Keywords:mathematics, operator theory, generalized bicircular projections, rank preserving maps, symmetric operators, antisymmetric operators
