Wedge (symbol)
Wedge (∧) is a symbol used to represent:
- Logical conjunction in propositional logic
- Meet in lattice theory
- Exterior product or wedge product in differential geometry.
In Unicode the symbol is encoded U+2227 ∧ LOGICAL AND (HTML ∧ · ∧) and by \wedge and \land in TeX. The opposite symbol (∨) is called a vel, or sometimes a (descending) wedge. Some authors who call the descending wedge 'vel' often call the ascending wedge ac (the corresponding Latin word for "and", also spelled "atque") keeping their usage parallel.
The wedge looks similar to the caret (^).
