Calderón-Zygmund estimates for quasilinear elliptic double obstacle problems with variable exponent and logarithmic growth (Q2211453)

In this paper, the authors study a very general elliptic equation with nonstandard growth of a kind of variable exponent coupled with a logarithmic type in order to establish an optimal Calderón-Zygmund theory by identifying a possibly minimal regularity requirement on the elliptic operator as well as on the boundary of the bounded domain with the desired higher maximality estimate.
