Fig. 1From: Stability of the stationary solutions of neural field equations with propagation delaysPlot of the first 200 eigenvalues of A in the scalar case (p=1, d=1) and L 0 =Id, J(x)=−1+1.5cos(2x). The delay function τ(x) is the π periodic saw-like function shown in Figure 2. Notice that the eigenvalues accumulate at λ=−1.Back to article page
