| Abstract: |
| This talk considers coexistence steady states of a prey-predator model with a strongly coupled diffusion term describing a predators` ability to chase preys. The first topic is the bifurcation structure of steady states and the second topic is the asymptotic behavior of steady states as a coefficient of the strongly coupled diffusion term tends to infinity. A main result asserts that coexistence steady states of the prey-predator model can approach coexistence steady states of an equal diffusive competition model as the coefficient tends to infinity. |
