Algebraic and Turing Separability of Rings
Journal of Algebra, 1996 A weak presentation of a countable field/ring \(F\) is an injective homomorphism from \(F\) into a field/ring whose universe is \(\mathbb{N}\) such that all the field/ring operations are translated by total recursive functions. Given two recursive integral domains \(R_1\) and \(R_2\) with quotient field \(F_1\) and \(F_2\) respectively, in this paper ...

When are the classes of Gorenstein modules (co)tilting?
Comptes Rendus. MathématiqueFor the class of Gorenstein projective (resp. injective and flat) modules, we investigate and settle the questions when the middle class is tilting and the other ones are cotilting. The applications have in three directions.

Jonsson Groups rings and Algebras
Irish Mathematical Society Bulletin, 1996 This well-written succinct survey article deals with the question: for which infinite cardinals is there a Jonsson algebra, that is, an algebra with no proper subalgebras of the same cardinality. The first two sections are self-contained and survey the basic results as they stood before pcf theory; in particular the proof is given that there is a ...

Computably Enumerable Semisimple Rings
MathematicsThe theory of semisimple rings plays a fundamental role in noncommutative algebra. We study the complexity of the problem of semisimple rings using the tools of computability theory. Following the general idea of computably enumerable (c.e.

Invariants of automorphic lie algebras [PDF]
Automorphic Lie Algebras arise in the context of reduction groups introduced in the late 1970s [35] in the field of integrable systems. They are subalgebras of Lie algebras over a ring of rational functions, denied by invariance under the action of a ...

Applications of Normal Forms for Weighted Leavitt Path Algebras: Simple Rings and Domains
, 2017 Weighted Leavitt path algebras (wLpas) are a generalisation of Leavitt path algebras (with graphs of weight 1) and cover the algebras LK(n, n + k) constructed by Leavitt.
