K algebra homomorphism
Webb4 sep. 2009 · Obviously, any isomorphism is a homomorphism— an isomorphism is a homomorphism that is also a correspondence. So, one way to think of the "homomorphism" idea is that it is a generalization of "isomorphism", motivated by the … Webba k A k-algebra homomorphism f : A B is a map between k-algebras that is both k-linear and a ring homomorphism.

WebbAn algebra homomorphism from a k-algebra to the endomorphism algebra of a vector space over k is called a representation of the algebra. Given a ring homomorphism f : R → S, the set of all elements mapped to 0 by f is called the kernel of f. The kernel is a two-sided ideal of R.
