A Real Representation Method for Solving Yakubovich‐j‐Conjugate Quaternion Matrix Equation

open access: yesAbstract and Applied Analysis, Volume 2014, Issue 1, 2014., 2014
A new approach is presented for obtaining the solutions to Yakubovich‐j‐conjugate quaternion matrix equation X−AX∧B=CY based on the real representation of a quaternion matrix. Compared to the existing results, there are no requirements on the coefficient matrix A.

A New Solution to the Matrix Equation X−AX¯B=C

open access: yesThe Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
We investigate the matrix equation X−AX¯B=C. For convenience, the matrix equation X−AX¯B=C is named as Kalman‐Yakubovich‐conjugate matrix equation. The explicit solution is constructed when the above matrix equation has unique solution. And this solution is stated as a polynomial of coefficient matrices of the matrix equation.

Finite Iterative Algorithm for Solving a Complex of Conjugate and Transpose Matrix Equation

open access: yesJournal of Discrete Mathematics, Volume 2013, Issue 1, 2013., 2013
We consider an iterative algorithm for solving a complex matrix equation with conjugate and transpose of two unknowns of the form: A1VB1+C1WD1+A2V¯B2+C2W¯D2+A3VHB3+C3WHD3+A4VTB4 + C4WTD4 = E. With the iterative algorithm, the existence of a solution of this matrix equation can be determined automatically.

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.

On j-conjugate product of quaternion polynomial matrices

open access: yes, 2013
In this paper, the concept of j-conjugate product over quaternion polynomial matrices is proposed. Further, some interesting properties of the proposed j-conjugate products are derived. By means of j-conjugate product, necessary and sufficient conditions
