Title: | Effects of a Degeneracy in the Competition Model Part II.: Perturbation and Dynamical Behaviour | Contributor(s): | Du, Y (author) | Publication Date: | 2002 | Open Access: | Yes | DOI: | 10.1006/jdeq.2001.4075 | Handle Link: | https://hdl.handle.net/1959.11/453 | Abstract: | This is the second part of our study on the competition model where the coefficient functions are strictly positive over the underlying spatial region Ω except b(x), which vanishes in a nontrivial subdomain of Ω, and is positive in the rest of Ω. In part I, we mainly discussed the existence of two kinds of steady-state solutions of this system, namely, the classical steady-states and the generalized steady-states. Here we use these solutions to determine the dynamics of the model. We do this with the help of the perturbed model where b(x) is replaced by b(x)+ε, which itself is a classical competition model. This approach also reveals the interesting relationship between the steady-state solutions (both classical and generalized) of the above system and that of the perturbed system. | Publication Type: | Journal Article | Source of Publication: | Journal of Differential Equations, 181(1), p. 133-164 | Publisher: | Academic Press | Place of Publication: | United States of America | ISSN: | 1090-2732 0022-0396 |
