Functions of least gradient and 1-harmonic functions
In this paper, we find the Euler-Lagrange equation corresponding to functions of least gradient. It turns out that this equation can be identified with the 1-Laplacian. Moreover, given a Lipschitz domain Ω, we prove that there exists a function of least gradient in Ω that extends every datum belongi...
