A diffusive tuberculosis model with fast and slow progression is investigated. By using sub-super solution method, Schauder’s fixed point theorem and Lyapunov functional, we obtain that there exists a traveling wave solutions (TWS) for the model if the threshold number and , where is the minimum wave speed.

研究了具有快速和缓慢进展的扩散性结核病模型。通过使用亚超解法,Schauder不动点定理和Lyapunov泛函,我们获得了该模型存在阈值的行波解(TWS)。 和 ,在哪里 是最小波速。
