$D$-Stratification and Hierarchy Graphs of the Space of Order 2 and 3 Matrix Pencils
Small changes in the entries of a matrix pencil may lead to important changes in its Kronecker normal form. Studies about the effect of small perturbations have been made when considering the stratification associated with the strict equivalence between ...

Generalized trace pseudo-spectrum of matrix pencils
The objective of the study was to investigate a new notion of generalized trace pseudo-spectrum for an matrix pencils. In particular, we prove many new interesting properties of the generalized trace pseudo-spectrum.

Positivity and Asymptotic Stability of Descriptor Linear Systems with Regular Pencils
The positivity and asymptotic stability of the descriptor linear continuous-time and discrete-time systems with regular pencils are addressed. Necessary and sufficient conditions for the positivity and asymptotic stability of the systems are established ...

A new method is proposed of design of regular positive and asymptotically stable descriptor systems by the use of state-feedbacks for descriptor continuous-time linear systems with singular pencils.

Definitizable hermitian matrix pencils
The paper presents three characterizations of strongly definitizable pencils, which generalize the classical results for definite pencils. They are in particular stably simultaneously diagonable. Also this form of stability is discussed with respect to an open subset of the real line. Implications for some quadratic eigenvalue problems are included.

Abstract Divergent thinking (DT) is an important constituent of creativity that captures aspects of fluency and originality. The literature lacks multivariate studies that report relationships between DT and its aspects with relevant covariates, such as cognitive abilities, personality traits (e.g. openness), and insight. In two multivariate studies (N

Efficient Parameter Estimation and Implementation of a Contour Integral-Based Eigensolver
We consider an eigensolver for computing eigenvalues in a given domain and the corresponding eigenvectors of large-scale matrix pencils. The Sakurai-Sugiura (SS) method is an eigensolver based on complex moments given by contour integrals of matrix ...

Classical orthogonal polynomials and Leverrier-Faddeev algorithm for the matrix pencils sE−A
In this contribution we present an extension of the Leverrier-Faddeev algorithm for the simultaneous computation of the determinant and the adjoint matrix B(s) of a pencil sE−A where E is a singular matrix but det(sE−A)≢0. Using a previous result by the

On the Reduction of Singular Matrix Pencils [PDF]
The following rational method of dealing with the reduction of a singular matrix pencil to canonical form has certain advantages. It is based on the principle of vector chains, the length of the chain determining a minimal index. This treatment is analogous to that employed by Dr A. C.
