In this paper, we study the global regularity estimates in Lorentz spaces for gradients of solutions to quasilinear elliptic equations with measure data of the form
− div ( 𝒜 ( x , ∇ u ) ) = μ in Ω , u = 0 on ∂ Ω ,
where μ is a finite signed Radon measure in Ω , Ω ⊂ ℝ n is a bounded domain such that its complement ℝ n ∖ Ω is uniformly p -thick and 𝒜 is a Carathéodory vector-valued function satisfying growth and monotonicity conditions for the strongly singular case 1 < p ≤ 3 n − 2 2 n − 1 . Our result extends the earlier results [19, 22] to the strongly singular case 1 < p ≤ 3 n − 2 2 n − 1 and a recent result [18] by considering rough conditions on the domain Ω and the nonlinearity 𝒜 .
