Propagating front in a homogeneous network. Propagating front in a homogeneous network with Gaussian weights (Equation 2.6) and piecewise linear rate function (Equation 2.3). Parameter values are W0 = 1.2, σ = 1, and κ = 0.4. (a) Snapshots of wave profile at time intervals of width Δt = 5 from t = 10 to t = 40. (b) Space-time contour plot. Wave speed asymptotically approaches the minimum c0 of the velocity dispersion curve given by Equation 2.12.
