Jordan triple product homomorphisms
Bojan Kuzma, 2006, original scientific article

Abstract: Nondegenerate mappings that preserve Jordan triple product on ▫${\mathscr{M}}_n({\mathbb{F}}$▫ are characterized. Here, ▫$n \ge 3$▫ and ▫$\mathbb{F}$▫ is an arbitrary field.
Keywords: mathematics, linear algebra, matrix algebra, Jordan triple product, nonlinear preserver

Ob otobraženijah, sohranjajuščih immananty
Bojan Kuzma, 2007, original scientific article

Abstract: V članku študiramo preslikave, ki transformirajo eno imananto matričnih snopov v drugo. Vnaprej ne predpostavimo niti surjektivnosti, niti linearnosti preslikav. Predpostavimo zgolj šibko linearnost v obliki identitete ▫$d_chi (Phi(A) + lambda Phi(B)) = d_{chi'}(A+lambda B)$▫. Pokažemo, da zgolj ta identiteta implicira avtomatično linearnost in bijektivnost preslikave ▫$Phi$▫.
Keywords: matematika, linearna algebra, teorija matrik, imanante, ohranjevalci
