    Characterizations and perturbation analysis of a class of matrices related to core-EP inverses 
    Zhou, Mengmeng; Chen, Jianlong; Thome, Néstor (Elsevier, 2021-09)
    [EN] Let A, B is an element of C-nxn with ind(A) = k and ind(B) = s and let L-B = (BB)-B-2(sic). A new condition (C-s,C-*): R(A(k)) boolean AND N((B-s)*) = {0} and R(B-s) boolean AND N((A(k))*) = {0}, is defined. Some new ...

    Generalized core inverses of matrices 
    Xu, Sanzhang; Chen, Jianlong; Benítez López, Julio; Wang, Dingguo (Miskolc University Press, 2019)
    [EN] n this paper, we introduce two new generalized inverses of matrices, namely, the < i, m >-core inverse and the (j, m)-core inverse. The < i, m >-core inverse of a complex matrix extends the notions of the core inverse ...
