WebThe previous example is in fact properly thought of as a de ning action. If V is a vector space of nite dimension nover the real numbers, then GL(V) is de ned as the group of vector space isomorphisms from V to itself (multiplication is composition). So there is a de ning action of GL(V) on V. By the choice of a basis for V, we may WebThe group G(S) is always nite, and we shall say a little more about it later. 7. The remaining two examples are more directly connected with group theory. If Gis a group, then Gacts on itself by left multiplication: gx= gx. The axioms of a group action just become the fact that multiplication in Gis associative (g 1(g 2x) = (g 1g 2)x) and the ...
