Linear and Multilinear Algebra

The aim of this article is to discuss -Jordan Lie triple systems, which are a generalization of Lie triple systems. Cohomological characterizations of -Jordan Lie triple systems are established, then deformations, Nijenhuis operators, Abelian extensions and -extensions of -Jordan Lie triple systems are studied using cohomology.

The aim of this paper is to study the q-numerical radius ωq(.) of bounded linear operators on Hilbert spaces. More precisely, first, we show that ωq(.) defines a norm which is equivalent to the operator norm. Next, the following compatible generalization of Kittaneh's inequality 14(q2−q2)2∥T∗T+TT∗∥≤ωq2(T)≤(q+21−q2)22×‖T∗T+TT∗‖.is obtained. Finally, some generalizations of q-numerical radius inequalities for composition of operators are established.

Perturbation theory plays a crucial role in sensitivity analysis, which is extensively used to assess the robustness of numerical techniques. To quantify the relative sensitivity of any problem, it becomes essential to investigate structured condition numbers (CNs) via componentwise perturbation theory. This paper addresses and analyses structured mixed condition number (MCN) and componentwise condition number (CCN) for the Moore-Penrose (M-P) inverse and the minimum norm least squares (MNLS) solution involving rank-structured matrices, which include the Cauchy-Vandermonde (CV) matrices and {1,1}-quasiseparable (QS) matrices. A general framework has been developed to compute the upper bounds for MCN and CCN of rank deficient parameterized matrices. This framework leads to faster computation of upper bounds of structured CNs for CV and {1,1}-QS matrices. Furthermore, comparisons of obtained upper bounds are investigated theoretically and experimentally. In addition, the structured effective CNs for the M-P inverse and the MNLS solution of {1,1}-QS matrices are presented. Numerical tests reveal the reliability of the proposed upper bounds as well as demonstrate that the structured effective CNs are computationally less expensive and can be substantially smaller compared to the unstructured CNs.
