Wave propagation under curvature effects in a heterogeneous medium. (English) Zbl 0878.35009
This paper is concerned with the evolution of an interface propagating with a curvature-dependent speed, in a heterogeneous medium. The model equation is of quasilinear parabolic type with a curvature coefficient $$\varepsilon$$. Working in a periodic context, we show the convergence of the solution of the initial-boundary value problem to a travelling wave solution. The behaviour of the corresponding steady speed is also investigated as $$\varepsilon$$ goes to zero and we recover known results concerning the resulting Hamilton-Jacobi equation.
