A class of singular Ro-matrices and extensions to semidefinite linear complementarity problems [PDF]

open access: yesYugoslav Journal of Operations Research, 2013
For ARnxn and qRn, the linear complementarity problem LCP(A, q) is to determine if there is xRn such that x ≥ 0; y = Ax + q ≥ 0 and xT y = 0. Such an x is called a solution of LCP(A,q).

Inverse scattering and the Geroch group [PDF]

open access: yesJournal of High Energy Physics, 2013
We study the integrability of gravity-matter systems in D=2 spatial dimensions with matter related to a symmetric space G/K using the well-known linear systems of Belinski-Zakharov (BZ) and Breitenlohner-Maison (BM). The linear system of BM makes the group structure of the Geroch group manifest and we analyse the relation of this group structure to the

M-matrix and inverse M-matrix extensions

open access: yesSpecial Matrices, 2020
A class of matrices that simultaneously generalizes the M-matrices and the inverse M-matrices is brought forward and its properties are reviewed. It is interesting to see how this class bridges the properties of the matrices it generalizes and provides a

Gait Event Prediction Using Surface Electromyography in Parkinsonian Patients

open access: yesBioengineering, 2023
Gait disturbances are common manifestations of Parkinson’s disease (PD), with unmet therapeutic needs. Inertial measurement units (IMUs) are capable of monitoring gait, but they lack neurophysiological information that may be crucial for studying gait ...

The group inverse of circulant matrices depending on four parameters

open access: yesSpecial Matrices, 2021
Explicit expressions for the coefficients of the group inverse of a circulant matrix depending on four complex parameters are analytically derived. The computation of the entries of the group inverse are now reduced to the evaluation of a polynomial ...

The (2,2,0) group inverse problem [PDF]

open access: yesApplied Mathematics and Computation, 2010
The authors characterize the existence of the group inverse of the block matrix \[ M=\left( \begin{matrix} A & C \\ B & 0 \end{matrix} \right), \] with zero \((2,2)\) entry, over a ring by means of the existence of the inverse of a suitable expression of the other three blocks \(A\), \(B\), \(C\) and their g-inverses, such as inner inverses or Drazin ...

Resistance Distance and Kirchhoff Index of $Q$ -Double Join Graphs

open access: yesIEEE Access, 2019
Let Q(G) be the graph derived from G by inserting a new vertex into every edge of G and by connecting edges of these new vertices that are on adjacent edges of G, and Q-double join of G, G1 and G2 denoted by GQ v{G1, G2}, is the graph derived from Q(G ...
