“…By assumption, the set Reg(f ) of regular points of f included in {x ∈ Ω |f > 0} is an open set of full measure in {x ∈ Ω |f > 0}. As a consequence, we deduce that f * is continuously differentiable on an open set of full measure of {f * > 0} and satisfies the inequality (4.3) thanks to the coarea formula and the isoperimetric inequality (we refer to [6] for more details). We conclude that {f > 0} is a ball, using a decreasing sequence of regular values which goes to 0 and the case of equality in the isoperimetric inequality.…”

“…The set of functions which satisfy the assumptions of Lemma 4.4 contains the smooth functions with compact support and only nondegenerate critical points; therefore it is dense in H 1 0 (Ω) (see [6] and the references herein). 4.2.…”
