TODO: Flesh out this page - I created it only to document the $a\vee b:=\max(a,b)$ seen in Probability and Stochastics

Definition

Traditionally:

• $$\max(x,y):=\left\{\begin{array}{lr}x & \text{if }x\ge y\\ y & \text{otherwise}\end{array}\right.$$
• $$\min(x,y):=\left\{\begin{array}{lr}x & \text{if }x\le y\\ y & \text{otherwise}\end{array}\right.$$
