在W^1,p(x)空间框架下研究了具有p(x)增长条件的椭圆型偏微分方程:-diva(x,u,Du)+g(x,u,(↓△)u)=f,得到了在W^10,p(x)空间中弱解的存在性,推广了Boccardo等关于在Sobolev空间中弱解的相应结论.
In this paper the elliptic partial differential equations satisfying p(x) growth conditions: - diva(x,u,Du) + g(x,u,↓△) = fare stadied in the setting of W^1,p(x) space, and the existence of weak solutions in W^10,p(x) is obtained which generalizes the corresponding work of Baccardo et al for the weak solutions in Sobolev space.
