摘要
The nonlinear stability of traveling waves for a multi-type SIS epidemic model is investigated in this paper. By using the comparison principle together with the weighted energy function, we obtain the exponential stability of traveling wavefront with large wave speed. The initial perturbation around the traveling wavefront decays exponentially as x -> -infinity, but it can be arbitrarily large in other locations.
