Jordan structures of nilpotent matrices in the centralizer of a nilpotent matrix with two Jordan blocks of the same sizeBogdanić, Duško (Avtor) Ðurić, Alen (Avtor) Koljančić, Sara (Avtor) Oblak, Polona (Avtor) Šivic, Klemen (Avtor) nilpotent matrixcentralizernilpotent orbitIn this paper we characterize all nilpotent orbits under the action by conjugation that intersect the nilpotent centralizer of a nilpotent matrix B consisting of two Jordan blocks of the same size. We list all the possible Jordan canonical forms of the nilpotent matrices that commute with B by characterizing the corresponding partitions.20242024-03-25 14:16:21Članek v reviji155307UDK: 512.64ISSN pri članku: 0024-3795DOI: 10.1016/j.laa.2024.03.008COBISS_ID: 190118403sl
