Locally standard measure algebras
Oksana Bezushchak, Bogdana Oliynyk
We parameterize countable locally standard measure algebras by pairs of a Steinitz number and a real number greater or equal to 1. This is an analog of the theorems of J.Dixmier an…
Hamming spaces and locally matrix algebras
Oksana Bezushchak, Bogdana Oliynyk
We introduce an abstract definition of a Hamming space that generalizes standard Hamming spaces . We classify countable locally standard Hamming spa…
Morita equivalent unital locally matrix algebras
Oksana Bezushchak, Bogdana Oliynyk
We describe Morita equivalence of unital locally matrix algebras in terms of their Steinitz parametrization. Two countable dimensional unital locally matrix algebras are Morita equ…
On primary decompositions of unital locally matrix algebras
Oksana Bezushchak, Bogdana Oliynyk
We construct a unital locally matrix algebra of uncountable dimension that (1) does not admit a primary decomposition, (2) has an infinite locally finite Steinitz number. It gives…
Unital locally matrix algebras and Steinitz numbers
Oksana Bezushchak, Bogdana Oliynyk
An -algebra with unit is said to be a locally matrix algebra if an arbitrary finite collection of elements from lies in a subalgebra wit…
