Asymptotic Isometries for Lacunary Muntz Spaces and Applications
INTEGRAL EQUATIONS AND OPERATOR THEORY
Authors: Gaillard, Loic; Lefevre, Pascal
Abstract
We prove that the normalized sequence ((pn+1)1/ptn))nZ in Lp([0,1]), up to some truncation, is asymptotically isometric to the canonical basis of p if and only if it is almost isometric if and only if (n+1/p)n (resp. (n)n) is a super-lacunary sequence. This extends recent results of the same authors. Similar results occur in C([0,1]). As a particular application, we get that all the (strict) s-numbers of the classical Cesaro operator on Lp are equal to p when p is an element of(1,+ infinity).

Abstract
Key opinion leaders in sport and exercise nutrition advocate for a personalised and periodised approach to dietary assessment and prescription. However, practice has not advanced to this level, making recommendations from key researchers unexploited in the applied setting. Our objective was to advance traditional nutritional assessment methods (data collection and analysis) of athletic populations to place training and competition stimulus at the core of a personalised, periodised approach. We term this approach peri-training nutrition (PIN). Novelty The PIN assessment allows researchers and practitioners to effect monitor habitual nutritional practices of athletes specific to athlete aims, training adaptation stimuli, and competitive events.
