AVERAGING ON COMPACT LIE GROUPS Let G denote a
... Let X be a set on which a Lie group G acts transitively, and let x0 be a point of X. If K = Gx0 = {g ∈ G : g(x0 ) = x0 }, then there is a bijection ϕ of the coset space G/K onto X given by ϕ(g) = g(x0 ). It is known that the coset space G/K has the structure of a C∞ manifold of dimension dim G − dim ...

... Remark: Similarity of matrices [see p. 145 of the textbook] is much stronger than the similarity of triangles you learned in geometry, where two triangles are similar if they have the same shape even if they have different sizes. Similarity of matrices is much more like congruence of triangles wher ...
