Everything about Outermorphism
Unital algebra homomorphism of exterior algebras
In geometric algebra, the outermorphism of a linear function between vector spaces is a natural extension of the map to arbitrary multivectors. It is the unique unital algebra homomorphism of exterior algebras whose restriction to the vector spaces is the original function. An outermorphism is also known as an exomorphism because it preserves the structure of the exterior product. Wikipedia →
