Algebraic Aspects of Dimension,ct, the situation becomes more complicated in comparison with the simplest examples: we will see that there exist various ways of expressing the ‘dimension’ of rings or modules as a number, and various analogues of finite dimensionality.

Noncommutative Rings, they are used in the study of the structure of a linear transformation, which depends in an essential way on the multiplicity of roots of its minimal polynomial. The same two operations, together with a passage to limits, make it possible to define analytic functions of a (real or complex) matrix.

Division Algebras of Finite Rank,ative algebra or Galois theory, and that of division algebras of finite rank over a field which is its centre. If an algebra . of finite rank over a field . has . as its centre, then we say that . is a . over ..

Examples of Groups: Infinite Discrete Groups,are called discrete in the first case, and continuous in the second. The simplest example of a discrete group is the infinite cyclic group, whose elements are of the form .. where . runs through all the integers.

General Results of Group Theory,mber of elements, there are only finitely many nonisomorphic groups of a given order; ideally one would like a rule specifying all finite groups of given order. For fairly small orders this can be done without much difficulty, and we run through the groups which arise.
