摘要：This paper is concerned with the stability of traveling front solutions for a viscous Fisher-KPP equation. By applying geometric singular perturbation method, special Evans function estimates, detailed spectral analysis and C-0 semigroup theories, each traveling front solution with wave speed c < -2 root f'(0) is proved to be locally exponentially stable in some appropriate exponentially weighted spaces.
