where g is a Lipschitz function on dQ. There we employed the ideas of Kohn and Strang [KS] to construct the solution by requiring each level set to have area-minimizing boundary relative to certain obstacles. This investigation and the techniques used therein led us to consider various questions related to the perhaps more natural problem of least gradient. That is, for a bounded Lipschitz domain Ω c R, and for g: δ Ω -> R continuous, we consider the problem
