Core-EP decomposition and related relations revisitedDolinar, Gregor (Avtor) Marovt, Janko (Avtor) Mosić, Dijana (Avtor) core-EP decomposition∗-ringpartial ordercore orderminus orderstar orderWe study relations that are induced by the core-EP decomposition. We revisit the core-EP preorder and extend the concepts of the core-minus, the c-minus, and the c-star partial orders from the set of all $n \times n$ complex matrices to the set of all core-EP invertible elements in a $\ast$-ring. Several characterizations of these relations are presented and thus some known results are generalized.20262026-07-23 12:30:54Neznano31264UDK: 512.554ISSN pri članku: 1306-6048DOI: 10.24330/ieja.1892320COBISS_ID: 285790467sl
