Jordan homomorphisms on triangular matricesBenkovič, Dominik (Avtor) matematikaalgebra zgornje trikotnih matrikjordanski homomorfizemjordansko odvajanjemathematicstriangular matrix algebraJordan homomorphismJordan derivationLet ▫${mathcal{T}}_n(mathcal{C})$▫ be the algebra of all ▫$n times n$▫ upper triangular matrices over a commutative unital ring ▫$mathcal{C}$▫. We describe the structure of Jordan homomorphisms from ▫${mathcal{T}}_n(mathcal{C})$▫ into an arbitrary algebra over ▫$mathcal{C}$▫. As an application a new proof of our recent result on Jordan derivations on ▫${mathcal{T}}_n(mathcal{C})$▫ is obtained. 20052015-07-10 14:52:07Članek v reviji51503sl
