Cet article considère un analogue de l’irrégularité des ensembles discrets. Si X est un espace compact et x:[0,1]→X est une fonction continue (interprétée comme équation d’un mouvement), la discrépance mesure la différence entre le temps de séjour de x(t) dans certains sous-ensembles et le volume de ces sous-ensembles. Le but essentiel de cet article est de démontrer des estimations inférieures de la discrépance par une fonction de la longueur de l’arc de x(t), 0≤t≤1. De plus on démontre que les estimations sont optimales à des facteurs logarithmiques près.

This paper deals with a continuous analogon to irregularities of point distributions. If a continuous fonction x:[0,1]→X where X is a compact body, is interpreted as a particle’s movement in time, then the discrepancy measures the difference between the particle’s stay in a proper subset and the volume of the subset. The essential part of this paper is to give lower bounds for the discrepancy in terms of the arc length of x(t), 0≤t≤1. Furthermore it is shown that these estimates are the best possible despite of logarithmic factors.
