Commutators of elementary matrices

WebApr 1, 2024 · We note that matrices are also used in [13] to write commutators in -algebras as linear combinations of projections. Having as a starting point the proof of [16, Theorem 4], in this note we use the commutators to provide decompositions of matrices over general rings, Corollary 2.3. This result is then used to obtain the following results. WebDec 1, 1990 · In linear algebra, one writes an invertible matrix as a product of elementary matrices. One can ask how many elementary matrices (or commutators) are needed to represent any product of elementary matrices (respectively, commutators).
