This study investigates a diffusive tuberculosis model with fast and slow progression, and shows the existence of traveling wave solutions (TWS) if the threshold number R0 is greater than 1 and the wave speed c is higher than the minimum wave speed c*.
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 R-0 > 1 and c > c*, where c* is the minimum wave speed.
