Webbwhere C 1 and C 2 are determined from knowledge of the Turing spaces of the systems concerned. We now state the direct problem: (DP) For given parameters (c 1,c 2) belonging to the admissible set U ad, find the morphogen concentrations u(x,t) and v(x,t) satisfying (1) with kinetics (i) or (ii) for all (x,t) 2X [0,T).

In particular, this model is well-known as a model in pattern formation. Thus u(x,t)and v(x,t)represent the density of two chemical substances at t≥0and x∈(−1,1)and ε2>0and D>0are diffusion coefficients of uand v, respectively.

We rigorously prove the existence of a steady-state spike cluster consisting of N spikes near a non-degenerate local minimum point t 0 of the smooth positive inhomogeneity μ(x), i.e. we assume that μ′(t 0) = 0, μ″(t 0) > 0 and we …
