Definite Conditions and Asymptotic Solution of One Nonlinear Partiai Differential Equation in Morphogenesis

Abstract:

      One reaction-diffusion equation φ_tx+εφ_tφ_xx-φ_xxx=γ(φ_x) has been presented in the study of Morphogenesis. In this paper, reasonable de-finite conditions of the equation are proposed and the asymptotic form of its solution is obtained by using perturbation method. So the existence of solution of this probiem is solved.
