Figure 1: Random walk in the Weyl chamber of the dual of SU(3)
Figure 2: On the left, a generic walk of P c (µ+ν = 1/3) ; on the right, an example of walk of P α,0 (λ = α(α−1/2)/[2−α+2α 2 ], µ = (α/2)/[2−α+2α 2 ] and ν = (1−α/2)/[2−α+2α 2 ]) Our first result deals with the Green functions – below, (X, Y ) denotes the
Figure 3: The uniformization space C ∪ {∞}, with on the left some important elements of it, in the middle the corresponding elements through the uniformization (x, y), and on the right the images of the cone F = {x exp(ıθ) : x ≥ 0, −π/3 ≤ θ ≤ 0} through th
