Topic: No bigoperators for union, intersection, and, or?
Kevin Cheung (Mar 12 2024 at 19:40):
I see that there are big operators for product and sum. But there don't seem to be big operators for union, intersection, conjunction, and disjunction. Is that right?

Like docs#iUnion or docs#sUnion ?
Eric Wieser (Mar 12 2024 at 19:43):
Those exist, they are ⋃
, ⋂
, ∀
, and ∃

Ha. How did I miss that!
Kevin Cheung (Mar 12 2024 at 19:43):
Thanks.
Kevin Cheung (Mar 12 2024 at 19:45):
What about conjunction and disjunction?
Ruben Van de Velde (Mar 12 2024 at 19:45):
What Eric said - that's forall and exists
Kevin Cheung (Mar 12 2024 at 19:46):
I see.

Conjunction and disjunction are ∧ (\and) and ∨ (\or) respectively

Those are the binary versions, not the n-ary ones
