||Nonlinear gradient estimates for elliptic double obstacle problems with measure data
||JOURNAL OF DIFFERENTIAL EQUATIONS, 2021
||We study quasilinear elliptic double obstacle problems with a variable exponent growth when the righthand side is a measure. A global Calder & oacute;n-Zygmund estimate for the gradient of an approximable solution is obtained in terms of the associated double obstacles and a given measure, identifying minimal requirements for the regularity estimate.
