Mesh of a partition

Builds on Partition of an interval

Definition

Let P=(x0,…,xn)P = (x_0, \dots, x_n) be a partition of [a,b][a, b]. The mesh of PP is ∥P∥=max⁡1≤i≤n(xi−xi−1),\| P \| = \max_{1 \le i \le n} (x_i - x_{i-1}), the length of the longest subinterval of PP.

Remarks

Refining a partition does not increase its mesh. The Riemann integral is a limit of Riemann sums as the mesh tends to 00. For the partition of [0,1][0, 1] into nn equal pieces, the mesh is 1/n1/n.
