Abstract. The main aim of the paper is to study some quantitative aspects of the stability of the weak fixed point property for nonexpansive maps in l1 (shortly, w-fpp). We focus on two complementary approaches to this topic. First, given a predual X of l1 such that the σ(l1, X)-fpp holds, we precisely establish how far, with respect to the Banach-Mazur distance, we can move from X without losi...

In this research complexation of dioxovanadium(V) with nitrilotriacetic acid (NTA) at differentionic strengths (0.1 to 1.0 mol dm-3) of sodium perchlorate as supporting electrolyte and pH rangeof 1.00-2.50 at 25 °C has been investigated by a combination of potentiometric and UVspectrophotometric measurements. Stability constants of two species, V0211L- and VO2H2L havebeen calculated. Ionic stre...
