Banach algebras associated with linear operator pencils

Mathematical Notes, 2009
Given complex linear spaces \(X\) and \(Y\), linear subspaces \(X_{F},X_{G}\) of \(X\), and linear operators \(F: X_{F}\to Y\) and \(G:X_{G}\to Y\), the operator pencil is defined as the function \(\lambda\in{\mathbb C}\mapsto\lambda F-G\), where \(\lambda F-G: X_{*}=X_{F}\cap X_{G}\to Y\). The author describes a commutative Banach algebra generated by

Generalized weighted core inverse in Banach *-algebras

Filomat
In this paper, we introduce the notion of the generalized weighted core inverse in a Banach *-algebra. We characterize this new generalized inverse by using the generalized weighted core decompo-sition and present the representations by the generalized ...

Amenability of Banach algebras of compact operators

, 1992
In this paper we study conditions on a Banach spaceX that ensure that the Banach algebraК(X) of compact operators is amenable. We give a symmetrized approximation property ofX which is proved to be such a condition.

Banach manifolds of algebraic elements in the algebra $$\mathcal{L}$$ (H) of bounded linear operatorsof bounded linear operators

Central European Journal of Mathematics, 2005
Given a complex Hilbert space H, we study the manifold\(\mathcal{A}\) of algebraic elements in\(Z = \mathcal{L}\left( H \right)\). We represent\(\mathcal{A}\) as a disjoint union of closed connected subsets M of Z each of which is an orbit under the action of G, the group of all C*-algebra automorphisms of Z.

Hermitian operators and isometries on algebras of matrix-valued Lipschitz maps

Linear and multilinear algebra, 2018
This paper deals with hermitian operators and surjective linear isometries, between spaces of Lipschitz maps, defined on a compact metric space, with values in a finite dimensional vector space. These spaces are endowed with the sum norm.
