On \(\aleph _0\) -Categorical Biregular Rings
摘要
We present a classification of \({\aleph _{0}}\) -categorical biregular rings, extending the work of Macintyre and Rosenstein (J Algebra 43:129–154) to the realm of non-commutative rings. It shall be shown that any countable \({\aleph _{0}}\) -categorical biregular ring with identity is a finite direct sum of filtered Boolean powers, the functions of each component taking values in suitable matrix algebras over finite fields.
