Webtopological group which is invariant under arbitrary left (right) translations-the left (right) Haar measure. (For ' translation' read ' rotation' in our particular case !) A sufficient condition for left and right Haar measures to coincide in a unique Haar measure is that the topological group be compact (cf. Halnos, p. 265, (5e)).

Web2. Unitary Invariant Ensembles. We begin with a brief overview of how the eigenvalues of a UIE are reduced to a determinantal point process. The eigenvectors of any UIE are simply Haar distributed unitary matrices1. Upon integrating out the eigenvectors, the distribution of the eigenvalues is determined to be [9, Section 5.4] 1 Z^ n Y i WebIt sometimes matters whether we use the left-invariant or right-invariant Haar measure. For example, the left and right invariant Haar measures on the affine group are not equal. Berger (1985, p. 413) argues that the right-invariant Haar measure is the correct choice.
WebThe only explicit description of the Haar measure on SO(n) that I'm aware of is inductive and based on hyperspherical coordinates on the unit (n − 1) -sphere Sn − 1. The idea is to first perform an arbitrary rotation of the first n − 1 coordinates, and then perform a rotation that maps en to any possible location on Sn − 1.
