Directly, w=[[0,1],[-1,0]] belongs to SU(2), is not in M, and satisfies wa_tw^{-1}=a_{-t}. For t>0, the usual residual ambiguity in the positive Cartan decomposition is by M.

The section and its regularity must match the external theorem. In addition, the decomposition is stated only outside K, whereas the target sums over every \u03b3\u2208\u0393, including the identity.
