In the preface I have given a brief discussion of what an algebraic group is and how to recognise one. The remainder of the notes are devoted to giving some of the most commonly-used examples and to developing some basic theory: they cover the group G = SL 2(R) = PSL 2(R), the Klein four-group, and a number of basic endomorphisms of complex projective space CP.

A linear equation a x + b y = c , is called a system of two or two-line equations. There are many methods for solving systems of linear equations; i.e., for finding all the values of x and y such that both equations will be satisfied simultaneously. If the coefficients of each equation are not both zero, there can be two or more “solutions” to a system of linear equations (corresponding to two or more different combinations of values for x and y which produce the same pair of linear equations).
