Steffensen method for solving nonlinear matrix equation $X+A^T X^{(-1)}A=Q$
In this article we study Steffensen method to solve nonlinear matrix equation $X+A^T X^{(-1)}A=Q$, when $A$ is a normal matrix. We establish some conditions that generate a sequence of positive denite matrices which converges to solution of this equation.
متن کاملA Note on the Bounded Solutions to x ′ ′ + c ( t , x , x ′ ) + q ( t )
Kroopnick (2010) discussed the bounded solutions of certain non-autonomous differential equations of the second order by using the integral test. In this paper, instead of the integral test, we study the results of Kroopnick [9] by using the Liapunov’s function approach. We compare the established results with that of Kroopnick [9]. We also give some additional results on the equi-bounded solut...
متن کاملOn the Dynamics of the Family axd(x − 1) + x
In this paper we consider the dynamics of the real polynomials of degree d + 1 with a fixed point of multiplicity d ≥ 2. Such polynomials are conjugate to fa,d(x) = axd(x−1)+x, a ∈ R{0}, d ∈ N. Our aim is to study the dynamics fa,d in some special cases.
متن کاملHyperbolicity of the family $f_c(x)=c(x-frac{x^3}{3})$
The aim of this paper is to present a proof of the hyperbolicity of the family $f_c(x)=c(x-frac{x^3}{3}), |c|>3$, on an its invariant subset of $mathbb{R}$.
