The blow-up analysis on $\mathbf{B}_2^{(1)}$ affine Toda system: Local mass and affine Weyl group

In this talk, I shall report a result on the affine Toda system with singularity, where the relation between the quantization information from the blow up analysis and the associated algebraic structure for the B_2^{(1)} Toda system is presented. This is a joint work with L.L. Cui, J.C. Wei and L. Zhang.
