Algebras
... As derivations are less classical objects, we shall give proofs of their basic properties. Definition 1.2.1 An endomorphism D of an algebra A is called a derivation of A if the equality D(xy) = xD(y) + D(x)y holds for all (x, y) ∈ A2 . Proposition 1.2.2 The kernel of a derivation of A is a subalgebr ...
