Abstract | dc.description.abstract | A two-species Lotka-Volterra competition-diffusion model with spatially inhomogeneous reaction tenns is investigated. The two species are assumed to be identical except for their interspecific competition coefficients. Viewing their common diffusion rate mu as a parameter, we describe the bifurcation diagram of the steady states, including stability, in terms of two real functions of mu. We also show that the bifurcation diagram can be rather complicated. Namely, given any two positive integers l and b, the interspecific competition coefficients can be chosen such that there exist at least l bifurcating branches of positive stable steady states which connect two semi-trivial steady states of the same type (they vanish at the same component), and at least b other bifurcating branches of positive stable steady states that connect semi-trivial steady states of different types. | en |
