=== Multi-Event Segment ===

A ''multi-event segment''

<math>(z_1,t_1)(z_2,t_2) \cdots (z_n,t_n)</math> over an event set <math> Z </math> and a time interval <math>[t_l, t_u] \subseteqsubset \mathbb{T} </math> is concatenations of [[Event Segment#Unit Event Segment|unit event segments]] <math>\epsilon_{[t_l,t_1]},(z_1,t_1), \epsilon_{[t_1,t_2]},(z_2,t_2),\ldots, (z_n,t_n),</math> and <math>\epsilon_{[t_n,t_u]}</math> where

<math>t_l\le t_1 \le t_2 \le \cdots \le t_{n-1} \le t_n \le t_u</math>.
