WebA rational number is a number that can be express as the ratio of two integers. A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number. Web13 nov. 2014 · If you have a rational number q ≠ 0, it is very natural to consider the automorphism g q: Q → Q given by x ↦ q x. It is easily shown that f ( q) = g q is then an injective group homomorphism. The last thing to do then is show that f is surjective. So, if you start with an automorphism g: Q → Q, you really want to show that g = g q for ...
