WebUsing this theorem the job of finding the supremum of lower sums (or infimum of upper sums) is reduced to finding the limit of corresponding sums as norm of partition tends to $0$. In particular we can take a sequence of partitions which are uniform (all subintervals of equal length) such that number of subintervals tends to $\infty $ . WebJan 26, 2024 · the lower sum of f with respect to the partition P is defined as L (f, P) = dj (xj - xj-1) where dj is the infimum of f (x) in the interval [xj-1, xj].
