Change of Variable for Multi-dimensional Integral

Isidore Fleischer

The change of variable theorem is proved under the sole hypothesis of differentiability of the transformation. Specifically, it is shown under this hypothesis that the transformed…

L1 Compactness of Bounded BV Sets

Isidore Fleischer

Functions, uniformly bounded in $B V$ norm in some bounded open set $U$ in $R^{n}$ , are compact in $L_{1} (U)$ . This result is known when $U$ has Lipschitz boundary [EG Th. 4 p. 176], [G…

Green's theorem with no differentiability

I. Fleischer

The result is established for a Jordan measurable region with rectifiable boundary. The integrand F for the new plane integral to be used is a function of axis-parallel rectangles,…
