Sekundarni naslov: | Aditivne preslikave, ki ne povečujejo ranga ena na hermitskih matrikah nad obsegom GF(2[sup]2) |
Sekundarni povzetek: | A complete classification of additive rank-one nonincreasing maps on hermitian matrices over Galois field ▫$GF(2^2)$▫ is obtained. This field is special and was not covered in a previous paper. As a consequence, some known applications, like the classification of additive rank-additivity preserving maps, are extended to arbitrary fields. An application concerning the preservers of hermitian varieties is also presented. |
