Abstract

In this paper we consider bubbling solutions to the general Liouville system: Δ_g u_i^k+∑_j=1ⁿ a_ijρ_j^k(\frach_j e^u_jk∫ h_j e^u_jk-1)=0\quadinM, i=1,...,n (n≥ 2) where (M,g) is a Riemann surface, and A=(a_ij)_{n× n} is a constant non-negative matrix and ρ_j^k→ ρ_j as k→ ∞. Among other things we prove the following sharp estimates. The location of the blowup point. The convergence rate of ρ_j^k-ρ_j, j=1,..,n. These results are of fundamental importance for constructing bubbling solutions. It is interesting to compare the difference between the general Liouville system and the SU(3) Toda system on estimates (1) and (2).
