题目:Linear vs. nonlinear speed selection of the front propagation into unstable states

报告人:周茂林 研究员 南开大学

摘要:In this talk, we consider the speed selection problem of the scalar reaction-diffusion equations and the Lotka-Volterra competition systems. Compared with the classical result on single equations in [Lucia-Muratov-Novaga, CPAM 2004], we propose a sufficient and necessary criterion to this long-standing problem of monostable dynamical systems for the first time. Moreover, our results can further reveal the essence of the linear determined problem from a new viewpoint on the decay rate of travelling wave solutions.
