A Note on the Solutions of Some Linear Octonionic Equations [PDF]

open access: yes, 2014
The main concerns of this paper are the linear equations with one term and one unknown of the forms: a(xa) =r, a(xb ) = r and (ax)b =r, and the linear equations with two terms and one unknown of the forms: (ax)b +(g x)d =r and a (xb )+g (xd ) =r over the

A canonical form for matrices under consimilarity

open access: yesLinear Algebra and its Applications, 1988
Complex \(n\times n\) matrices A, B are said to be consimilar if \(B=S^{- 1}A\bar S\) for some non-singular complex matrix S. This concept arises naturally from comparing the expressions for a semilinear transformation on an n-dimensional complex vector space in two different coordinate systems.

RNA‐Based Assessment of Diversity and Composition of Active Archaeal Communities in the German Bight

open access: yesArchaea, Volume 2012, Issue 1, 2012., 2012
Archaea play an important role in various biogeochemical cycles. They are known extremophiles inhabiting environments such as thermal springs or hydrothermal vents. Recent studies have revealed a significant abundance of Archaea in moderate environments, for example, temperate sea water.

Geometric polarimetry - part II: the Antenna Height Spinor and the Bistatic Scattering Matrix [PDF]

open access: yes, 2017
This paper completes the fundamental development of the basic coherent entities in Radar Polarimetry for coherent reciprocal scattering involving polarized wave states, antenna states and scattering matrices. The concept of antenna polarization states as

On the Solutions of Some Linear Complex Quaternionic Equations [PDF]

open access: yes, 2014
Some complex quaternionic equations in the type AX-XB= C are investigated. For convenience, these equations were called generalized Sylvester-quaternion equations, which include the Sylvester equation as special cases.

Regularizing algorithm for mixed matrix pencils [PDF]

open access: yes, 2017
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.

Cycles of linear and semilinear mappings

open access: yes, 2012
We give a canonical form of matrices of a cycle of linear or semilinear mapping V_1 --- V_2 --- ... --- V_t --- V_1 in which all V_i are complex vector spaces, each line is an arrow ---> or

Stratification theory of matrix pairs under equivalence and contragredient equivalence [PDF]

open access: yes, 2019
We develop the theory of perturbations of matrix pencils basing on their miniversal deformations. Several applications of this theory are given. All possible Kronecker pencils that are canonical forms of pencils in an arbitrary small neighbourhood of ...
