【摘要】 <正> 考虑对角性拟线性椭园组 -Dβ(Aαβ(x,u)Dαui)=Bi(x,u,Du),x∈Ω,i=1,…,N。 (1)这里Ω是Rn中的有界域。重复上、下标α、β表示从1到n求和,Du={Dαui|α=1,…
【Abstract】 Consider the quasilinear elliptic systems in diagonal form -Dβ(Aαβ(x,u)Dαui)=Bi(x,u,Du) x∈Ω?Rn,i=1,…,N As we know, under the natural growth condition, the weak solutionu of (1) isbounded, i.e. u∈H1∩L∞. In this paper, we weaken the bound-edness of solution uto finite integrability, i.e, u∈H1∩Ln(r-1)/(2-r),1+2/n<r<2. We prive the C0,α and C1,αeverywhere regularity for weak solutions of (1).
