Abstract: |
It is proved that if $E\subset {\bold R},F\subset {\bold R}^n$,
then $ \Cal P(E\times F,\varphi_1\varphi_2)\leq c\cdot \Cal P(E,\varphi_1)
\Cal P(E,\varphi_2)$,
where $\Cal P(\cdot ,\varphi )$ denotes the $\varphi$-packing measure,
$\varphi$ belongs to a class of Hausdorff functions, the positive constant
$c$ deponds only on $\varphi_1,\varphi_2$ and $n$. |
Keywords: |
