چکیده

This article deals with some complementarity properties of Z and Lyapunov-like transformations on a symmetric cone. Similar to the results proved for Lyapunov and Stein transformations on Herm(Rn×n), we show that for Lyapunov-like transformations, the P and S properties are equivalent, and that for a Ztransformation, the S-property implies the P-property of a transformation that is (quadratically) similar to the given transformation. In addition, we show that a Lyapunov-like transformation is the sum of a Lyapunov transformation and a derivation.

Z-transformations on proper and symmetric cones Z-transformations

Motivated by the similarities between the properties of Z-matrices on Rn + and Lyapunov and Stein transformations on the semidefinite cone S+, we introduce and study Z-transformations on proper cones. We show that many properties of Z-matrices extend to Z-transformations. We describe the diagonal stability of such a transformation on a symmetric cone by means of quadratic representations. Final...

A full NT-step O(n) infeasible interior-point method for Cartesian P_*(k) –HLCP over symmetric cones using exponential convexity

In this paper, by using the exponential convexity property of a barrier function, we propose an infeasible interior-point method for Cartesian P_*(k) horizontal linear complementarity problem over symmetric cones. The method uses Nesterov and Todd full steps, and we prove that the proposed algorithm is well define. The iteration bound coincides with the currently best iteration bound for the Ca...

On the bilinearity rank of a proper cone and Lyapunov-like transformations

A real square matrix Q is a bilinear complementarity relation on a proper cone K in R if x ∈ K, s ∈ K∗, and 〈x, s〉 = 0⇒ xQs = 0, where K∗ is the dual of K [14]. The bilinearity rank of K is the dimension of the space of all bilinear complementarity relations on K. In this article, we continue the study initiated in [14] by Rudol et al. We show that bilinear complementarity relations are related...

Some Global Uniqueness and Solvability Results for Linear Complementarity Problems Over Symmetric Cones

This article deals with linear complementarity problems over symmetric cones. Our objective here is to characterize global uniqueness and solvability properties for linear transformations that leave the symmetric cone invariant. Specifically, we show that, for algebra automorphisms on the Lorentz space Ln and for quadratic representations on any Euclidean Jordan algebra, global uniqueness, glob...

A Note on the Paper "Linear Complementarity Problems Over Symmetric Cones: Characterization of Qb-Transformations and Existence Results"

This paper is devoted to the study of the symmetric cone linear complementarity problem (SCLCP). In this context, our aim is to characterize the class Qb in terms of larger classes, such as Q and R0. For this, we introduce the class F and Garćıa’s transformations. We studied them for concrete particular instances (such as second-order and semidefinite linear complementarity problems) and for sp...
