  We provide sparse estimates for gradients of solutions to divergence form
elliptic partial differential equations in terms of the source data. We give a
general result of Meyers (or Gehring) type, a result for linear equations with
VMO coefficients and a result for linear equations with Dini continuous
coefficients. In addition, we provide an abstract theorem conditional on PDE
estimates available. The linear results have the full range of weighted
estimates with Muckenhoupt weights as a consequence.
