The mesh of a partition of an interval is defined as the maximum distance between two consecutive points of the partition, $$ \operatorname{mesh}(P) := \max_{i\ge 1}(x_i-x_{i-1}) \quad\text{where \( P = (x_0, x_1, \dotsc, x_n) \) and \( x_0 < x_1 < \dotsb < x_n \)}. $$ I was wondering if there is a specific terminology for the minimum such distance, $ \min_{i\ge 1}(x_i-x_{i-1}) $.
Thank you for any answer or insight you may have.
