Convergence of the transition density to stationarity as time evolves, for initial frequencies x = (0.02, 0.02, 0.96)^T. Deviation from the stationary density is measured by ${\Vert d(t;\mathbf{x},·)\Vert }_{1/\mathrm{\Pi }}^2$, defined in (29). The mutation rates were chosen to be θ = (0.01, 0.02, 0.03) and the selection parameters were σ = 0.1σ₁, σ = 0.5σ₁ and σ = 0.1σ₁, respectively. The truncation level was set to D = 40, and (29) was approximated by summing over 0 ≤ n ≤ 561 and m, k such that 0 ≤ |m|, |k| ≤ 36.
