We study the coexistence problem when a third species w invades an eco-system consisting of two species u and v, where u, v and w compete with one another. Even if the influence of w on u and v is quite small under suitable conditions, we show that the three species can co-existence as a traveling wave on the real line R. Our approach uses the results by Berestycki et al.(2009) and provides a method to construct 3-species non-monotone traveling wave solutions. This is a joint work with Chueh-Hsin Chang, Li-Chang Hung, Masayasu Mimura and Toshiyuki Ogawa.
