Some linear preserver problems on upper triangular matricesMolnár, Lajoš ; Šemrl, PeterV članku študiramo linearne ohranjevalce na trikotnih matrikah. Karakteriziramo obrnljive linearne preslikave, ki ohranjajo idempotente ranga 1 ali komutativnost. S primeri pokažemo, da je ... predpostavka bijektivnosti potrebna za rezultate.Source: Linear and Multilinear Algebra. - ISSN 0308-1087 (Let. 45, št. 2-3, 1998, str. 189-206)Type of material - article, component partPublish date - 1998Language - englishCOBISS.SI-ID - 8569689
