A Genuine Extension of The Moore-Penrose Inverse to Dual Matrices
Chunfeng Cui, Liqun Qi
The Moore-Penrose inverse is a genuine extension of the matrix inverse. Given a complex matrix, there uniquely exists another complex matrix satisfying the four Moore-Penrose condi…
Dual Number Matrices with Primitive and Irreducible Nonnegative Standard Parts
Liqun Qi, Chunfeng Cui
In this paper, we extend the Perron-Frobenius theory to dual number matrices with primitive and irreducible nonnegative standard parts. One motivation of our research is to conside…
Eigenvalues and Jordan Forms of Dual Complex Matrices
Liqun Qi, Chunfeng Cui
Dual complex matrices have found applications in brain science. There are two different definitions of the dual complex number multiplication. One is noncommutative. Another is com…
A Power Method for Computing the Dominant Eigenvalue of a Dual Quaternion Hermitian Matrix
Chunfeng Cui, Liqun Qi
In this paper, we first study the projections onto the set of unit dual quaternions, and the set of dual quaternion vectors with unit norms. Then we propose a power method for comp…
