On sum of a nilpotent and an ideally finite algebras
We study associative algebras \(R\) over arbitrary fields which can be decomposed into a sum \(R=A+B\) of their subalgebras \(A\) and \(B\) such that \(A^{2}=0\) and \(B\) is ideally finite (is a sum of its finite dimensional ideals). We prove that \(R\) has a locally nilpotent ideal \(I\) such tha...

Algebra and Discrete Mathematics| Summary: | We study associative algebras \(R\) over arbitrary fields which can be decomposed into a sum \(R=A+B\) of their subalgebras \(A\) and \(B\) such that \(A^{2}=0\) and \(B\) is ideally finite (is a sum of its finite dimensional ideals). We prove that \(R\) has a locally nilpotent ideal \(I\) such that \(R/I\) is an extension of ideally finite algebra by a nilpotent algebra. Some properties of ideally finite algebras are also established. |
