We study the following question: suppose that A and ℬ are two algebras of complex n × n matrices such that the ring commutator [A, B] = AB – BA is "small" for each A ∈ A and B ∈ ℬ; does this imply ...
The Journal of Operator Theory endeavours to publish significant articles in all areas of operator theory, operator algebras and closely related domains. All accepted manuscripts are carefully ...
Group gradings provide a powerful framework for decomposing algebraic structures into subspaces that are systematically indexed by a group. In the context of Lie algebras, which play a central role in ...
