Abstract

It is shown that solutions to the anisotropic least gradient problem for boundary data f ∈ Lp(∂Ω) lie in L(Np)/(N-1)(Ω); the exponent is shown to be optimal. Moreover, the solutions are shown to be locally bounded with explicit bounds on the rate of blow-up of the solution near the boundary in two settings: in the anisotropic case on the plane and in the isotropic case in any dimension.
