We consider the following Liouville system:{Δv1=2ev1+μev2+4πl=1mβ1,lδPlinR2,Δv2=2ev2+μev1+4πl=1mβ2,lδPlinR2,R2ev1dx<+,R2ev2dx<+, where 1=lmβ1,l=l=1mβ2,l. We show the existence of global branches of non-radial solutions with m=1, bifurcating from v1(x)=v2(x)=2αlog|xP1|+log64(1α)2(2+μ)(8+|xP1|2(1α))2 at the values μ=2n2+n2n2+n+2 for some special nN and β1,1=β2,1=α. We also show the existence and non-existence results with m3, under some suitable assumptions on β1,l,β2,l for l=1,,m.

Liouville方程和系统的存在结果

我们考虑以下Liouville系统:{-Δv1个=2Ëv1个+μËv2+4π=1个β1个δP[R2-Δv2=2Ëv2+μËv1个+4π=1个β2δP[R2[R2Ëv1个dX<+[R2Ëv2dX<+ 哪里 1个=β1个==1个β2。我们证明存在非径向解的全局分支=1个,从 v1个X=v2X=-2α日志|X-P1个|+日志641个-α22+μ8+|X-P1个|21个-α2 在价值 μ=-2ñ2+ñ-2ñ2+ñ+2 对于一些特殊的 ññβ1个1个=β21个=α。我们还显示了存在和不存在的结果3,在以下适当假设下 β1个β2 对于 =1个
