Some chain conditions on weak incidence algebras
Let X be any partially ordered set, R any commutative ring, and T = I * (X,R) the weak incidence algebra of X over R. Let Z be a finite nonempty subset of X, L(Z) = {x ∈ X : x z for some z ∈ Z}, and M = Te Z. Various chain conditions on M are investigated. The results so proved are used to construct some classes of right perfect rings that are not left perfect.
متن کاملMatrix Chain Models and Kac-moody Algebras
The Lie Algebras for the open, respectively closed, Matrix Chain Models offer an interesting laboratory for the study of various non-trivial mixtures of Heisenberg, KacMoody, and Virasoro algebras as well as sl(∞). The algebras are not only infinite dimensional but are rather unwieldy. Various restrictions may be imposed to cut down on the complexity, e.g. finite momentum P and small alphabets....
متن کاملChain Conditions for Leavitt Path Algebras
In this paper, results known about the artinian and noetherian conditions for the Leavitt path algebras of graphs with finitely many vertices are extended to all row-finite graphs. In our first main result, necessary and sufficient conditions on a row-finite graph E are given so that the corresponding (not necessarily unital) Leavitt path K-algebra L(E) is semisimple. These are precisely the al...

متن کاملOn Chain Varieties of Linear Algebras
In the present paper we study varieties of linear k-algebras over a commutative associative Noetherian ring k with 1, whose subvarieties form a chain. We describe these varieties in terms of identities in the following cases: residually nilpotent varieties, varieties of alternative, lordan and (1, l)-algebras.
