Query: Sharp estimates for the spreading speeds of the Lotka-Volterra
  competition-diffusion system: the strong-weak type   We consider the classical two-species Lotka-Volterra competition-diffusion
system in the strong-weak competition case. When the corresponding minimal
speed of the traveling waves is not linear determined, we establish the precise
asymptotic behavior of the solution of the Cauchy problem in two different
situations: (i) one species is an invasive one and the other is a native
species; (ii) both two species are invasive species.
