    Inverse eigenvalue problem for normal J-hamiltonian matrices 
    Gigola, Silvia Viviana; Lebtahi Ep-Kadi-Hahifi, Leila; Thome, Néstor (Elsevier, 2015-10)
    [EN] A complex square matrix A is called J-hamiltonian if AT is hermitian where J is a normal real matrix such that J(2) = -I-n. In this paper we solve the problem of finding J-hamiltonian normal solutions for the inverse ...

    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 ...

    When is the Hermitian/skew-Hermitian part of a matrix a potent matrix? 
    Ilisevic, Dijana; Thome, Néstor (ILAS–the International Linear Algebra Society, 2012)
    [EN] This paper deals with the Hermitian H(A) and skew-Hermitian part S(A) of a complex matrix A. We characterize all complex matrices A such that H(A), respectively S(A), is a potent matrix. Two approaches are used: ...
