If we imagine the space of all pure states as a sphere, the Haar measure is equivalent to picking a random point on the sphere. It can also be proved that there exists an essentially unique right-translation-invariant Borel measure , but it need not coincide with the left-translation-invariant measure . For instance, a measure of one unit is given by the segment running from (1,1) to (e,1/e), where e is Euler's number.

Then Vei[/x] v(Et-x) = 0. A singleton has exactly then a Hair measure non-zero if the group is discrete. Integrals and the Haar Measure In this and the next chapter, background material on integration, topological groups and group actions is presented. If G=R\{0} under multiplication, then dx/|x| is the Haar measure (check!). Example 13.4. a right Haar measure. In most cases, to induce a measure on X = G / H you can simply pick a fundamental domain F G, and integrate over it (according to this, this can be done at least when G is -compact). One consequence, for example, that every finite-dimensional complex representation of a compact group is unitary with respect to a suitable scalar product.
