积分方程组的Liouville型定理
Liouville type theorems for a system of integral equations
摘要
Abstract
Consider the following system of integral equations u(x) =∫Rn 1| x - y | n-αup1 (y)vp2 (y)dy , v(x) =∫Rn 1| x - y |n-αuq1 (y)vq2 (y)dy , w here 0<α< n ,1≤ pi ,qi≤(n+α)/(n-α) (i=1 ,2) .By using moving sphere method in inte‐gral forms and Hardy‐Littlewood‐Sobolev (HLS) inequality ,the positive solutions are classi‐fied with critical exponents ;moreover ,the nonexistence of positive solutions is also illustrated with subcritical exponents .关键词
