We study a free boundary problem of two competing species with latent heat effect. We establish the existence and uniqueness of the traveling wave solution and derive upper and lower bounds for the wave speed. Especially our results show that the latent heat retards propagation of the waves.

具有潜热效应的自由边界问题的行波解

我们研究了具有潜在热效应的两个竞争物种的自由边界问题。我们确定行波解的存在性和唯一性，并得出波速的上下界。尤其是我们的结果表明，潜热阻碍了波的传播。
