Descending wedge
The descending wedge symbol ∨ may represent:
- Logical disjunction in propositional logic
- Join in lattice theory
- The wedge sum in topology
- The V sign, a symbol representing peace among other things
The ∨ symbol was introduced by Russell and Whitehead in Principia Mathematica, where they called it the Logical Sum or Disjunctive Function.
In Unicode the symbol is encoded. In TeX, it is
\vee or \lor.One motivation and the most probable explanation for the choice of the symbol ∨ is the latin word "vel" meaning "or" in the inclusive sense. Several authors use "vel" as name of the "or" function.
