wedge product

Exterior algebra operation

The wedge product is an operation in mathematics that combines vectors or differential forms to produce new objects of higher dimension.

Two vectors wedge together to give an oriented area; three give an oriented volume.

The wedge product is antisymmetric: swapping the order reverses the sign.

The wedge product of dx and dy gives the area element dx ∧ dy.

Central to differential geometry and physics, it generalizes the cross product to any number of dimensions.
