TITLE: What does ∧ mean in an equation?
QUESTION [5 upvotes]: Note that this is not a caret (^), but rather a ∧. I'm aware it's used as an "and" in logic, but that doesn't seem to fit the context.
Here are some examples it's used in.

REPLY [3 votes]: $\wedge$ is the wedge product which is the product in an exterior algebra.
