Non-Commutative Fejér Theorems

Integral Equations and Operator Theory, 2012
The author of the paper under review studies the problem of approximation of operators in the uniform Roe algebra \(C^{*}_u(G)\) by their truncations. Here, \(G\) is a finitely generated group. In particular, sufficient conditions for such approximability are obtained.

Theorems of Idempotent Commutative Groupoids

Algebra Colloquium, 2005
In this paper, among other results, we prove that a clone C with five essentially binary operations is minimal if and only if C is a clone of a non-trivial affine space over GF(7). This result is a product of systematic investigation of varieties of idempotent commutative groupoids.

Commutativity theorems

Proceedings of the 1999 international symposium on Symbolic and algebraic computation, 1999
Commutativity theorems are part of the study of polynomial identities in non-commutative rings. They are theorems which assert that, under certain conditions, the ring at hand must be commutative. The proofs of theorems of this sort in their general form require the structure theory for non-commutative rings. Instances of these theorems have a strongly
