摘要
This paper provides existence results for entropy solutions to elliptic problem with nonstandard growth and merely integrable data, -divA(x,u, backward difference u)-div phi(x,u)=fin omega,the growth of leading part of the operator is governed by a Musielak function whose growth does not have to be doubling and the lower-order term phi satisfies a generalized natural growth condition without any supplementary restrictions.
