Abstract

In this paper, we establish the higher differentiability of the gradient of solutions to variational obstacle problems of the type

min ⁡ { ∫ Ω F ⁢ ( x , u , D ⁢ u ) ⁢ 𝑑 x : u ∈ 𝒦 ψ ⁢ ( Ω ) } .

Here Ω ⊂ ℝ n is a bounded open set, ψ ∈ W 0 1 , q ⁢ ( Ω ) is a fixed function called obstacle, and 𝒦 ψ ⁢ ( Ω ) is the class of admissible functions. The main feature of the energy densities under consideration here is that they satisfy non-standard growth conditions with respect to the gradient variable and that they explicitly depend on the pair ( x , u ) . Assuming that ψ ∈ L loc ∞ ⁢ ( Ω ) ∩ W loc 2 , 2 ⁢ q - p ⁢ ( Ω ) , we are able to prove a second order regularity result for the solution.

Keywords: Elliptic equations; regularity of solutions; higher differentiability; obstacle problem
