“…In particular, when F = F (x, t, u), some non linear phenomena involve equation (1) both in superconductivity and biology and Dirichlet conditions in superconductivity refer to the phase boundary specifications [6,7,8,17], while in excitable systems occur when the pulse propagation in heart cells is studied [18]. Besides, Dirichlet problem is also considered for stability analysis and asymptotic behavior of reaction-diffusion systems solutions, [19,20], or in hyperbolic diffusion [21].…”
