英文摘要It is known that the one-dimensional nonlinear heat equation u(t) = f(u)(x1 x1), f' (u) > 0, u(+/-infinity, t) = u(+/-), u(+) not equal u(-) has a unique self-similar solution (u) over bar( x(1)/root 1+t). In multi-dimensional space, (u) over bar( x(1)/root 1+t) is called a planar diffusion wave. In the first part of the present paper, it is shown that under some smallness conditions, such a planar diffusion wave is nonlinearly stable for the nonlinear heat equation: u(t) - Delta f(u) = 0, x is an element of R-n. The optimal time decay rate is obtained. In the second part of this paper, it is further shown that this planar diffusion wave is still nonlinearly stable for the quasilinear wave equation with clamping: u(tt) + u(t) - Delta f(u) = 0, x is an element of R-n. The time decay rate is also obtained. The proofs are given by an elementary energy method.
