摘要
In this paper, we show the existence of weak solutions for steady flows of electrorheological fluids with nonhomogeneous Dirichlet boundary condition under the condition p(x) > 2n/n+ 2, n = 2, 3. In particular, we improve a priori estimate for weak solutions to the problem with min p(x) < 2, which is an improvement even for constant p. (C) 2017 Published by Elsevier Ltd.
