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 belonging to L(∂Ω). We show, as well, the non uniqueness of solutions in the case of discontinuous boundary values.
