报告摘要:In this talk, we will discuss the local masses of Toda system with $n\geq 2$. By using Pohozaev identity, the monodromy theory from complex ODE and some recent work by Eremenko-Gabrielov-Tarasov, we are able to determine the local masses for the system and it turns out that the local masses are closely related to the element in the Weyl group of the corresponding Lie algebra. Based on this quantization result, the a priori estimate and some existence results of this system are obtained.
