Note on Reflexivity and Invariant Means
Applying Šmulian Theorem, we show that if a Banach space X is not reflexive then the space of bounded functions from Z with values in X does not admit an invariant mean. Invariant means on amenable groups are an important tool in many parts of mathematics, especially in harmonic analysis (see [5, 6]). For basic properties of invariant means, we refer the reader to [5]. We would only like to men...
متن کاملA Characterization of Reflexivity
We give a characterization of reflexivity in terms of rotundity of the norm. Renorming characterization of various classes of Banach spaces is important and useful for applications. Some classes turn out to have very elegant descriptions, while most seem to resist the renorming point of view. The most spectacular result in this area is certainly the Enflo-Pisier characterization of superreflexi...
متن کاملKant and Hegel on Aesthetic Reflexivity
The paper aims at reevaluating a conception of the aesthetic that was developed by Kant and Hegel but that has been widely neglected due to the fact that their positions in aesthetics have been wrongly considered to be antagonistic to one another. The conception states that the aesthetic is a practice of reflecting on other human practices. Kant was the first to articulate this conception, but ...
متن کاملA note on vague graphs
In this paper, we introduce the notions of product vague graph, balanced product vague graph, irregularity and total irregularity of any irregular vague graphs and some results are presented. Also, density and balanced irregular vague graphs are discussed and some of their properties are established. Finally we give an application of vague digraphs.
متن کاملA note on lifting projections
Suppose $pi:mathcal{A}rightarrow mathcal{B}$ is a surjective unital $ast$-homomorphism between C*-algebras $mathcal{A}$ and $mathcal{B}$, and $0leq aleq1$ with $ain mathcal{A}$. We give a sufficient condition that ensures there is a proection $pin mathcal{A}$ such that $pi left( pright) =pi left( aright) $. An easy consequence is a result of [L. G. Brown and G. k. Pedersen, C*-algebras of real...
