非局部反应扩散方程的双稳态行波解

Bistable travelling waves for nonlocal reaction diffusion equations

Matthieu Alfaro, Jerome Coville, Gael Raoul

摘要:

研究一类具有双稳态和非局部非线性项的反应扩散方程的行波解,其中比较原理不成立。不假设平衡$u\equiv 1$的稳定性。我们构造一个行波解连接0到一个未知的稳定状态,这是“以上和远离”,从中间平衡。对于聚焦核,我们证明,正如预期的那样,波连接0到1。我们的结果也适用于非局部点火的情况。

英文摘要:

We are concerned with travelling wave solutions arising in a reaction diffusion equation with bistable and nonlocal nonlinearity, for which the comparison principle does not hold. Stability of the equilibrium $u\equiv 1$ is not assumed. We construct a travelling wave solution connecting 0 to an unknown steady state, which is "above and away", from the intermediate equilibrium. For focusing kernels we prove that, as expected, the wave connects 0 to 1. Our results also apply readily to the nonlocal ignition case.
