摘要
We deal with the traveling wave solutions (including periodic wave solutions, solitary wave solutions and kink or antikink solutions) of a generalized Burgers-Fisher equation via studying the dynamics of a related Lienard system. We obtain necessary and sufficient conditions for the Lienard system to have a unique limit cycle, a homoclinic loop and a heteroclinic loop, respectively.(c) 2023 Elsevier Inc. All rights reserved.
