Web11 1. Add a comment. -1. There is a difference. Both products take two vectors in R 3. The cross product gives a vector in the same R 3 and the wedge product gives a vector in a different R 3. The two output vector spaces are indeed isomorphic and if you choose an isomorphism you can identify the two products. WebIdea. In fundamental physics the basic entities that are being described are called fields, as they appear in the terms classical field theory and quantum field theory.. General.
