    Characterizations of {K,s+1}-Potent Matrices and Applications 
    Lebtahi Ep-Kadi-Hahifi, Leila; Romero Martínez, José Oscar; Thome, Néstor (Elsevier, 2012-01-15)
    Recently, situations where a matrix coincides with some of its powers have been studied. This kind of matrices is related to the generalized inverse matrices. On the other hand, it is possible to introduce another class ...

    Matrices A such that RA = A^s+1 R when R^k = I 
    Lebtahi Ep-Kadi-Hahifi, Leila; Stuart, J.; Thome, Néstor; Weaver, J.R. (Elsevier, 2013-08)
    This paper examines matrices A is an element of C-nxn such that RA = A(s+1) R where R-k = I, the identity matrix, and where sand k are nonnegative integers with k >= 2. Spectral theory is used to characterize these matrices. ...

    On the spectra of some combinations of two generalized quadratic matrices 
    Petik, Tugba; OZDEMIR, Halim; Benítez López, Julio (Elsevier, 2015-10)
    [EN] Let A and B be two generalized quadratic matrices with respect to idempotent matrices P and Q, respectively, such that (A − αP)(A − βP) = 0, AP = PA = A, (B − γ Q)(B − δQ) = 0, BQ = QB = B, PQ = QP, AB = BA, and (A ...

    Relations between {K, s + 1}-potent matrices and different classes of complexmatrices 
    Lebtahi Ep-Kadi-Hahifi, Leila; Romero Martínez, José Oscar; Thome, Néstor (Elsevier, 2013)
    In this paper, {K, s + 1}-potent matrices are considered. A matrix A in C{nxn} is called {K, s + 1}-potent when KA^(s+1)K = A where K is an involutory matrix and s in {1, 2, 3, . . .}. Specifically, {K, s + 1}-potent ...

    The spectrum of matrices depending on two idempotents 
    Liu, Xiaoji; Benítez López, Julio (Elsevier, 2011-10)
    Let P and Q be two complex matrices satisfying P2=P and Q 2=Q. For a,b nonzero complex numbers such that aP+bQ is diagonalizable, we relate the spectrum of aP+bQ to the spectra of P-Q, PQ, PQP and PQ-QP. © 2011 Elsevier ...
