    Combined matrices of sign regular matrices 
    Bru García, Rafael; Gasso Matoses, María Teresa; Gimenez Manglano, María Isabel; Santana-De Asis, Máximo De Jesús (Elsevier, 2016-06-01)
    The combined matrix of a nonsingular matrix A is the Hadamard (entry wise) product C(A) = A ◦ (A−1)T . Since each row and column sum of C(A) is equal to one, the combined matrix is doubly stochastic when it is nonnegative. ...

    Nonnegative singular control systems using the Drazin projector 
    Herrero Debón, Alicia; Thome Coppo, Néstor Javier (Elsevier, 2013-07)
    In this work we study conditions for guaranteeing the nonnegativity of a discrete-time singular control system. A first approach can be found in the literature for general systems, using the whole coefficient matrices. ...

    On the stability and spectral radius of a finite set of matrices 
    Cantó Colomina, Begoña; Coll, Carmen; Sánchez, Elena (Taylor & Francis, 2016-03)
    This paper studies some problems related to the stability and the spectral radius of a finite set of matrices. A seasonal epidemic model is given to illustrate the use of the obtained results. In this example, the relationship ...

    Stabilization of an epidemic model via an n-periodic approach 
    Cantó Colomina, Begoña; Coll, Carmen; Sánchez, Elena (De Gruyter Open Sp. z o.o., 2018)
    [EN] We analyze the evolution of an infectious disease by combining different groups of a population when the route of transmission is via encounters with free-living virulent organisms that can survive for a long time ...
