A Hermitian canonical form for complex matrices under consimilarity
An algorithm is described that yields a Hermitian canonical form for complex matrices under consimilarity. It consists of three blocks corresponding to the nonnegative, negative and nonreal eigenvalues of \(A\bar A\). A similar algorithm produces a real canonical form (for complex matrices under consimilarity).

A Study on Commutative Elliptic Octonion Matrices
In this study, firstly notions of similarity and consimilarity are given for commutative elliptic octonion matrices. Then the Kalman-Yakubovich s-conjugate equation is solved for the first conjugate of commutative elliptic octonions. Also, the notions of

On the singular value decomposition of (skew-)involutory and (skew-)coninvolutory matrices
The singular values σ > 1 of an n × n involutory matrix A appear in pairs (σ, 1σ{1 \over \sigma }). Their left and right singular vectors are closely connected. The case of singular values σ = 1 is discussed in detail. These singular values may appear in

Some Equivalence Relations and Results over the Commutative Quaternions and Their Matrices
In this paper, we give some equivalence relations and results over the commutative quaternions and their matrices. In this sense, consimilarity, semisimilarity, and consemisimilarity over the commutative quaternion algebra and commutative quaternion ...

The Division Ring Over Conjugate Product
In this paper, we investigate the rational fractions in the framework of conjugate product and establish a division ring. Some conjugate properties on the proposed division ring are obtained, and the similarity and consimilarity properties are ...

Regularizing algorithm for mixed matrix pencils [PDF]
P. Van Dooren (1979) constructed an algorithm for computing all singular summands of Kronecker’s canonical form of a matrix pencil. His algorithm uses only unitary transformations, which improves its numerical stability.

In this paper, the consimilarity of complex matrices is generalized for the split quaternions. In this regard, coneigenvalue and coneigenvector are defined for split quaternion matrices. Also, the existence of solution to the split quaternion matrix equation X-AXB = C is characterized and the solution of the equation in the explicit form are derived ...

On (con)similarities and congruences between A and A^*, A^T or A
The complex consimilarity of complex matrices defined by \(\overline{P}^{-1} AP= B\), where \(A,B,P\in \mathbb{C}^{n\times n}\) and \(P\) is invertible, is not extensible to the quaternions since \(\overline{AB}\neq \overline{AB}\) in general. Thus, given quaternion matrices \(A,B\in \mathbb{H}^{n\times n}\), the author defines the \(j\)-conjugate of \(
