It is well-known that the -th Riemann sum of a compactly supported function on the real line converges to the Riemann integral at a much faster rate than the standard rate of convergence if the sum is over the lattice, . In this paper we prove an n-dimensional version of this result for Riemann sums over polytopes.
Il est bien connu que l’intégrale de Riemann d’une fonction d’une variable est beaucoup mieux approximée par la -ième somme de Riemann si la somme est effectuée sur le réseau . Dans cet article nous démontrons un résultat similaire en plusieurs variables pour des sommes de Riemann sur des polytopes.
Keywords: Riemann sums, Euler-Maclaurin formula for polytopes, Ehrhart’s theorem
Mot clés : sommes de Riemann, formule d’Euler-Maclaurin pour les polytopes, théorème de Ehrhart
