Jan 8, 2019 at 19:52 comment added Romeo Thanks a lot for your answer! I found rather surprising that very little is known on this topic, I did expect a huge literature on this. I will look through the papers you mentioned. A part from regularity, which seems out-of-reach, do you know whether some maximum principles are available in this setting? In the aforementioned paper by Bombieri & co. it is proved e.g. (using regularity) that if $U,V$ are open sets s.t. their boundaries of least area and $U,V$ coincide out of a compact then they are indeed equal $U=V$. Any ideas for a similar principle in anisotropic case? Thanks again.
