Exterior algebra

Uncommon card · No. 111610

In mathematics, the exterior algebra or Grassmann algebra of a vector space V {\displaystyle V} is an associative algebra that contains V , {\displaystyle V,} which has a product, called exterior product or wedge product and denoted with ∧ {\displaystyle \wedge } , such that v ∧ v = 0 {\displaystyle v\wedge v=0} for every vector v {\displaystyle v} in V . {\displaystyle V.} The exterior algebra is named after Hermann Grassmann, and the names of the product come from the "wedge" symbol ∧ {\displaystyle \wedge } and the fact that the product of two elements of V {\displaystyle V} is "outside"...
