Locally finite M-solid varieties of semigroups

open access: yes, 2003
An algebra of type τ is said to be locally finite if all its finitely generated subalgebras are finite. A class K of algebras of type τ is called locally finite if all its elements are locally finite. It is well-known (see [2]) that a variety of algebras

On Locally Nilpotent Derivations Of Fermat Rings

open access: yes, 2015
Let Bm n (Fermat ring), where m ≥ 2 and n ≥ 3. In a recent paper D. Fiston and S. Maubach show that for m ≥ n2 - 2n the unique locally nilpotent derivation of Bm n is the zero derivation.

The Measure Algebra of a Locally Compact Group

open access: yes, 1967
Let G be a locally compact group (= locally compact Hausdorff topological group). By the measure algebra of G we mean the Banach *-algebra M(G) of bounded regular Borel measures on G.

A theory of quaternionic algebra, with applications to hypercomplex geometry

open access: yes, 2000
In this paper we introduce a new algebraic device, which enables us to treat the quaternions as though they were a commutative field. This is of interest both for its own sake, and because it can be applied to develop an "algebraic geometry" of ...

Invariant subspaces for algebras of linear operators and amenable locally compact groups

open access: yes, 1988
Let G G be a locally compact group. We prove in this paper that G G is amenable if and only if the group algebra L 1 ( G )

M-infrabarrelledness and m-convexity

open access: yes, 2012
m-infrabarrelledness, in the context of locally convex algebras, is considered to prove results previously obtained for barrelled algebras. Thus, any unital commutative m-infrabarrelled advertibly complete and pseudocomplete locally m-convex algebra with

Structure of locally convex quasi C*-algebras

open access: yes, 2008
There are examples of C*-algebras A that accept a locally convex *-topology τ coarser than the given one, such that Ã[τ] (the completion of A with respect to τ) is a GB*-algebra. The multiplication of A[τ] may be or not be jointly continuous.

Multipliers in locally convex *-Algebras

open access: yes, 2013
We consider a complete locally m-convex *- Algebra with continuous involution, which is also a "perfect" projective limit, and describe its multiplier algebra, under a weaker topology, making it a locally C*-algebra.

Weakly almost periodic functionals on the measure algebra

open access: yes, 2010
It is shown that the collection of weakly almost periodic functionals on the convolution algebra of a commutative Hopf von Neumann algebra is a C*-algebra. This implies that the weakly almost periodic functionals on M(G), the measure algebra of a locally
