Stability of Real Parametric Polynomial Discrete Dynamical Systems [PDF]
Discrete Dynamics in Nature and Society, 2015 We extend and improve the existing characterization of the dynamics of general quadratic real polynomial maps with coefficients that depend on a single parameterλand generalize this characterization to cubic real polynomial maps, in a consistent theory that is further generalized to realmth degree real polynomial maps.

Matrix-valued Laurent polynomials, parametric linear systems and integrable systems [PDF]
Journal of the Franklin Institute, 2020 In this paper, we study transfer functions corresponding to parametric linear systems whose coefficients are block matrices. Thus, these transfer functions constitute Laurent polynomials whose coefficients are square matrices. We assume that block matrices defining the parametric linear systems are solutions of an integrable hierarchy called for us ...

Solving parametric polynomial systems
Journal of Symbolic Computation, 2007 The authors present a new algorithm for solving constructible or semi-algebraic systems in the indeterminates \([U,X]\) where \(U=[U_1,\dots ,U_d]\) is the set of parameters and \(X=[X_{d+1},\dots,X_n]\) the set of unknowns. To this end, they study the characterization of open subsets in the parameter space over which the number of solutions is ...

Solving parametric piecewise polynomial systems
Journal of Computational and Applied Mathematics, 2011 This paper establishes the basic theory on piecewise polynomial functions that are \(C^r\) with different smoothness degree \(r\) over the whole domain, and presents the theory and methods for solving zero-dimensional parametric piecewise polynomial systems. It shows that solving such a system amounts to solving \(m\) parametric semi-algebraic systems,
