If R T – AI has infinite codimension then there exists a sequence an in X such that, for all n, an is not in the subspace V. Then F is relatively compact in C K if and only if it satisfies the following two conditions: Then there exists a maximal left ideal L containing x. This result is true for U simply or finitely connected. Let r be a continuous irreducible representation of A on a Banach space X. It is easy to verify that I n I is an ideal of C K. His proof, which is not so easy, uses mainly representation theory see 12 , pp.

Thus 1 is true. Suppose moreover that the left multiplications x H xy and right multiplications x. Thus f x is invertible in A. Then Sp x and Spy contain a neighbourhood of 0.

In fact, this result is a corollary of a much more general result see Theorem 3. I’m trying to deploy new web application in Tomcat 6. Let L’ be a maximal left ideal of Al Rad A. Kaplansky conjectured that t2to same result is true for non-commutative semi-simple Banach algebras. Hence ep, E I.
Then for y E Ua-1 we have: Then, by Corollary 3. Such functions were studied for the first time by C. But the problem is sjp open for operators on a Hilbert Space.
Thus we get a contradiction and the proof is complete. In the theory of automatic continuity, the following problem has been known for a long time and remains unsolved: Since p is not isolated in E it is an interior point of E, hence t2t interior point of E’.
This idea originates from the pioneering work of F. Distribution of Values of Analytic Multifunctions Logic and Structure Devlin: This result is true for U simply or t2i connected. We now prove iii. Improving the question-asking experience. The results in this chapter will be used throughout the book.
Let I be a dosed two-sided ideal i of A.
t2tl This family is partially ordered by inclusion. Let f, be a sequence in the unit ball of X’. E X, the vectors a;, r a f and r a 2e are linearly dependent.

Istraj,escu proved Theorem 3. Except for finite-dimensional ones, the simplest non-commutative Banach algebra is. It is obvious that C is a closed subalgebra of E X containing the identity. Denote by e the element 0,1 of A. What can be said about this function a?
Definitions and General Properties If X isanon-empty open subset of a complete metric space then the union of a countable collection of closed subsets of X with empty interiors also has an empty interior. We now give some positive results.
