Groups of invertible elements of matrix rings

Siberian Mathematical Journal, 1999
Let \({\mathcal O}\subseteq\mathbb{Q}_n\) be an arbitrary finitely generated matrix ring over the rationals. The author presents an algorithmic description of the group of units \(U({\mathcal O})\) of this ring. If \(\mathcal O\) is a matrix ring irreducible over the rationals then the ring is a ring with almost solvable endomorphism group whenever the

INVERTIBLE COMMUTATORS IN MATRIX RINGS

Journal of Algebra and Its Applications, 2011
In a matrix ring R = 𝕄2(S) where S is a commutative ring, we study equations of the form XY - YX = U ∈ GL 2(S), focusing on matrices in R that can appear as X or as XY in such equations. These are the completable and the reflectable matrices in R.

Matrix Inverter: A Multilevel Inverter Based on Matrix Converter Switch Matrix

2020 IEEE Electric Power and Energy Conference (EPEC), 2020
This paper presents a new concept of matrix converter application as an inverter. A matrix converter is commonly used as an AC-to-AC conversion device. Hypothetically the AC sources of the matrix converter can be replaced with DC sources. By using a switching strategy similar to a multilevel inverter switching strategy, and some modification on the ...
