An introduction to linear algebra, suitable for students of science, engineering, economics,and statistics who are not maths specialists, but need this material for their work. The book discusses systems of linear equations and their solutions; and provides application for the linear algebra.

Fundamental to all areas of mathematics, algebra provides the cornerstone for the studenta s development. The concepts are often intuitive, but some can take years of study to fully absorb. For over twenty years, the authora s classic three--volume set, Algebra, has been regarded by many as the most outstanding introductory work available.

LINEAR equations play an important part, not only in mathe matics itself, but also in many fields in which mathematics is used. The actual pro cess of setting up the equations and of interpreting the solution is one which more properly belongs to that field, and in any case is a problem of a different nature altogether.

The theory of Lie groups rests on three pillars: analysis, topology and algebra. Correspondingly it is possible to distinguish several phases, overlapping in some degree, in its development. It also allows one to regard the subject from different points of view, and it is the algebraic standpoint which has been chosen in this tract as the most suitable one for a first introduction to the subject.
