1. Jordan [tau]-derivations of locally matrix ringsAjda Fošner, Chen-Lian Chuang, Tsiu Kwen Lee, 2013, izvirni znanstveni članek Opis: Let ▫$R$▫ be a prime, locally matrix ring of characteristic not 2 and let ▫$Q_{ms}(R)$▫ be the maximal symmetric ring of quotients of ▫$R$▫. Suppose that ▫$\delta \colon R \to Q_{ms}(R)$▫ is a Jordan ▫$\tau$▫-derivation, where ▫$\tau$▫ is an anti-automorphism of $R$. Then there exists ▫$a \in Q_{ms}(R)$▫ such that ▫$\delta(x) = xa - a\tau(x)$▫ for all ▫$x \in R$▫. Let ▫$X$▫ be a Banach space over the field ▫$\mathbb{F}$▫ of real or complex numbers and let ▫$\mathcal{B}(X)$▫ be the algebra of all bounded linear operators on ▫$X$▫. We prove that ▫$Q_{ms}(\mathcal{B}(X)) = \mathcal{B}(X)$▫, which provides the viewpoint of ring theory for some results concerning derivations on the algebra ▫$\mathcal{B}(X)$▫. In particular, all Jordan ▫$\tau$▫-derivations of ▫$\mathcal{B}(X)$▫ are inner if ▫$\dim_{\mathbb{F}} X>1$▫.

4. More language(s) - more space(s)?Nada Zerzer, 2009, izvirni znanstveni članek Opis: This article addresses the issue how heteroglossic people in the three regions of Carinthia, Primorska, and the Trst/Trieste region experience their multilingualism and its representations in everyday day life. The approach is transdisciplinary and includes theory and methods from fields of political theory, sociology of space, sociolinguistics, ethnography, visual cultures and multimodal discourse analysis. The research focus is on social constructions of space, created by heteroglossic people in their everyday life and by the representations of the languages in their living environment. This article wants to take a closer look at life with - or in - heteroglossia and at possible integrative handling of it

6. Reflexivity defect of spaces of linear operatorsJanko Bračič, Bojan Kuzma, 2009, izvirni znanstveni članek Opis: For a finite-dimensional linear subspace ▫{$\mathscr{S}} \subseteq {\mathscr{L}} (V,W)$▫ and a positive integer ▫$k$▫, the ▫$k$▫-reflexivity defect of ▫$\mathscr{S}$▫ is defined by ▫${\mathrm{rd}}_k ({\mathscr{S}}) = \dim({\mathrm{Ref}}_k (\mathscr{S})/\mathscr{S})$▫ where ▫${\mathrm{Ref}}_k$▫ is the ▫$k$▫-reflexive closure of ▫$\mathscr{S}$▫. We study this quantity for two-dimensional spaces of operators and for single generated algebras and their commutants.
