Stability of Traveling Wave Solution of 3 Species Competition Model
Shun-Chieh Wang (National Taiwan University)


The spectral theory is a basic technique to study the stability of ODE or PDE solutions. The key is to find the essential spectrum. In this talk, I will follow paper [1] to introduce the basic technique which help us to characterize the essential spectrum, and prove the stability of TWS in 3 species competition model.
