(L^p\) regularity of least gradient functions

It is shown that solutions to the anisotropic least gradient problem for boundary data \(f \in L^p(\partial\Omega)\) lie in \(L^{\frac{Np}{N-1}}(\Omega)\); 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...

description It is shown that solutions to the anisotropic least gradient problem for boundary data \(f \in L^p(\partial\Omega)\) lie in \(L^{\frac{Np}{N-1}}(\Omega)\); 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.
