| Abstract: |
| In this talk, I shall present some results on traveling wave solutions and asymptotic spreading. These systems do not generate monotone semiflows and are reducible at the unstable steady state. On the traveling wave solutions, we focus on minimal wave speed by presenting existence or nonexistence of traveling wave solutions. When the asymptotic spreading is concerned, we try to estimate different spreading speeds of different unknown functions governed by the same systems. |
