Isn't that the supremum operator??????
If so, I guess it is returning the highest number in the set uj1...ujl

PS:Guess is the keyword here...:)
yah thats what i thought too.. but then again its the supremum of whats inside those parentheses, and btw the supremum doesn't have to be in the set, since its a subset of a a partial order and the supremum is the least of those who are higher than all in the subset... but anyway the indices under the sup thats confusing me.
Supremum limit maybe? (shot in the dark)
