\subsection{\bf Basic Definitions---Borel Sets}
\begin{itemize}
\item Consider a variable point $X$ in space $Y$ where $Y$ is some subset of
$\Re_k$ ($\Re_k$ is the $k$ dimensional real Euclidean space).  

\item Further, consider the family of all Borel sets $S$ in $Y$.

\item You will, of course, recall that a Borel set is gotten by
performing (finite or denumerably many times) on intervals $[a, b]$,
$(a,b)$, $(a,b]$, $[a,b) \ldots$ the operations of addition,
subtraction or multiplication (and continuing process denumerably
often).
\end{itemize}
