If again (see section 3) ρ ∞ and ρ 0 are the liftings for functions in ℒ K ∞ (μ) and ℒ ℝ ¯ 0 (μ) uniquely generated by a lifting ρ ∈ Λ(μ), then ρ is left-translation invariant if and only if ρ ∞ and ρ 0 are such.. In the above definition we have fixed explicitly a Haar measure μ on X for easier reference. But the definition of a left-translation ...

Web1 Haar measure means the measure which is invariant under the group action. I did this by choosing a d d complex matrix X with entries chosen from the gaussian distribution (which is indeed invariant under U(d)) and then taking Y = X + Xy to make it hermitian, and then using the matrix U which diagonalizes Y. WebLet V be the m × m upper-left corner of an n × n Haar-invariant unitary matrix. Let λ1,··· ,λm be the eigenvalues of V. We prove that the empirical distribution of a normalization of λ1,··· ,λm goes to the circular law, that is, the uniform distribution on {z ∈ C; z ≤ 1} as m → ∞ with m/n → 0. We also prove that the ...
