研究一维欧几里德空间中非线性对流扩散方程行波的存在性和稳定性。扩散系数与拉普拉斯函数类似,依赖于梯度,可能是简并的。我们还证明了解收敛于匀速运动的界面外;我们的结果包括界面属性的产生和传播。特别地,对初始数据扰动建立了无条件稳定性。
We study existence and stability of travelling waves for nonlinear convection–diffusion equations in the one-dimensional Euclidean space. The diffusion coefficient depends on the gradient in analogy with the-Laplacian and may be degenerate. We also prove that the solution converges tooutside an interface which moves with constant velocity; our results include both generation and propagation of interface properties. In particular, unconditional stability is established with respect to initial data perturbations in.
