Amenability in Group Algebras and Banach Algebras.
MATHEMATICA SCANDINAVICA, 1994 There are many known examples of Banach algebras \(\mathfrak A\) that can be shown to be amenable by the construction of a dense-ranged homomorphism from the group algebra of an amenable group into \(\mathfrak A\). To answer the question of whether this criterion is necessary for amenability, many amenable Banach algebras are constructed for which ...

Completion of normed algebras of polunomials [PDF]
, 1975 Let P be the algebra of polynomials in one inderminate x over the complex field C. Suppose xs2225 · xs2225 is a norm on P such that the coefficient functionals cj: ∑αix1 → αj (j = 0,1,2,…) are all continuous with respect to xs2225·xs2225, and Let K ...

Perturbation for the Group Inverse in a Banach Algebra
We present new additive results for the group inverse in a Banach algebra under certain perturbations. The upper bound of ∥(a+b)#−ad∥ is thereby given. These results extend the main results presented by Liu, Qin, and Wei.

The Arens-Calderon theorem for commutative topological algebras
Extracta MathematicaeA theorem of Arens and Calderon states that if A is a commutative Banach algebra with Jacobson radical Rad(A), and if a0 , . . . , an∈ A with a0 ∈ Rad(A) and a1 an invertible element of k A, then there exists y ∈ Rad(A) such that Σ ak yk = 0.

On James' Quasi-Reflexive Banach Space as a Banach Algebra
, 1980 In [4] and [5], R. C. James introduced a non-reflexive Banach space J which is isometric to its second dual. Developing new techniques in the theory of Schauder bases, James identified J**, showed that the canonical image of J in J** is of codimension ...
