Abstract
In this note, our aim is to show that families of smooth hypersurfaces of Rn+1 which are all “C1 –close” enough to a fixed compact, embedded one, have uniformly bounded constants in some relevant inequalities for mathematical analysis, like Sobolev, Gagliardo– Nirenberg and “geometric” Calderòn–Zygmund inequalities.
