Commutative Algebra, field of complex numbers . has degree 2 over the field of real numbers . and infinite degree (or to be more exact, no finite degree) over the field of rational numbers .. An important property of finite extensions is expressed by the following lemma.

Associative Rings,es a precise meaning only by imposing certain definite restrictions. As an example of what is meant we offer the algebra A(.) of all associative non-commuting polynomials in . with coefficients from some field . of zero characteristic. Indeed, such an algebra is primitive.

Varieties of Algebras, = {.., .., ..} such that .. = ., ..(.) = .., ..(., .) = . (., . ∈ .). It is clear that not each universal algebra with such a set of operations is a group: as a matter of fact, nothing is said about the properties of the operations.

Lecture Notes in Computer Scienceis happens in the case of an arbitrary set . of pairwise commuting operators, i.e. for a set such that . − . = 0 for any . ∈ .. The generalization of this result brings a new operation, the commutator of linear operators, and, further, yields the concept of a (linear) Lie algebra.
