A universal primitive for functions of several variables
The authors construct an interval function F which is a universal primitive of measurable functions f defined in a compact of \(R^ n\), in the sense that for any such function there exists an infinitesimal sequence \((h_ n)\) for which \(f(x)=\lim \frac{F(x+h_ n)-F(x)}{h_ n}\).
