Are smooth compact surfaces embedded in R3 (with no boundary) , with bounded area, always the boundary of a finite perimeter set?
Take a smooth surface S in R3 embedded , with finite area. Can we say that the "interior" A of S is a Borel set? If yes, one can use the Gauss-Green Theorem to say that A has finite perimeter.
For example the sphere S^2 in R3 can be seen as the boundary of the open ball in R3; and so one can think of the ball as a finite perimeter set.
The bound on the area is fundamental, the embedded property assure that one can't have some issues with intersections. There are some problems with the orientability: for example the Mobius strip can be a counterexample if one allows S to be non-compact.
(finite perimeter set is on the distributional sense of GMT)
