给定一个紧致闭曲面ε,我们考虑ε上的广义户田方程组:− ε ui = ∑2 j=1 ρjaij(hje uj R ε hje uj dVg − 1),i = 1,2,其中ρ1,ρ2是真实的参数,h1,h2是光滑正函数.利用问题的变分结构,利用一个新的Minimax格式,我们证明了当ρ1和ρ2 < 4π时解的存在性.
Given a compact closed surface Σ, we consider the generalized Toda system of equations on Σ: −∆ui = ∑2 j=1 ρjaij ( hje uj R Σ hje uj dVg − 1 ) for i = 1, 2, where ρ1, ρ2 are real parameters and h1, h2 are smooth positive functions. Exploiting the variational structure of the problem and using a new minimax scheme we prove existence of solutions for generic values of ρ1 and for ρ2 < 4π.
