AbstractWe consider the following Toda system where γi>−1, δ0 is Dirac measure at 0, and the coefficients aij form the standard tri-diagonal Cartan matrix. In this paper, (i) we completely classify the solutions and obtain the quantization result: $$\sum_{j=1}^n a_{ij}\int_{\mathbb{R}^2}e^{u_j} dx = 4\pi(2+\gamma _i+\gamma_{n+1-i}), \quad\forall\;1\leq i \leq n.$$ This generalizes the classification result by Jost and Wang for γi=0, $\forall\;1\leq i\leq n$. (ii) We prove that if γi+γi+1+⋯+γj∉ℤ for all 1≤i≤j≤n, then any solution ui is radially symmetric w.r.t. 0. (iii) We prove that the linearized equation at any solution is non-degenerate. These are fundamental results in order to understand the bubbling behavior of the Toda system.
