|

all curves. Namely, the lower envelope of the set $\calC$ can be
|
||||
defined as the following function:
|
||||
\begin{eqnarray*}
|
||||
\calL_{\calC} (x) = \min_{1 \leq k \leq n}{\overline{C}_k (x)} \ ,
|
||||
\calL_{\calC} (x) = \min_{1 \leq k \leq n}{

\begin{ccHtmlOnly}<span style="text-decoration:overline">C</span>\end{ccHtmlOnly}
|
||||
_k (x)} \ ,
|
||||
\end{eqnarray*}
|
||||
where we define $\overline{C}_k(x) = C_k(x)$ for $x \in R_{C_k}$,
|
||||
and $\overline{C}_k(x) = \infty$ otherwise.
|
||||
where we define $
|
||||
\begin{ccTexOnly}\overline{C}\end{ccTexOnly}
|
||||
\begin{ccHtmlOnly}<span style="text-decoration:overline">C</span>\end{ccHtmlOnly}

_k(x) = C_k(x)$ for $x \in R_{C_k}$,

\begin{ccHtmlOnly}<span style="text-decoration:overline">C</span>\end{ccHtmlOnly}
|
||||
_k(x) = \infty$ otherwise.
|
||||
|
||||
Similarly, the {\em upper envelope} of $\calC$ is the point-wise maximum of
|
||||
the $x$-monotone curves in the set:
|
||||
\begin{eqnarray*}
|
||||
\calU_{\calC} (x) = \max_{1 \leq k \leq n}{\underline{C}_k (x)} \ ,
|
||||
\calU_{\calC} (x) = \max_{1 \leq k \leq n}{
|
||||
\begin{ccTexOnly}\underline{C}\end{ccTexOnly}
|
||||
\begin{ccHtmlOnly}<span style="text-decoration:underline">C</span>\end{ccHtmlOnly}
|
||||
_k (x)} \ ,
|
||||
\end{eqnarray*}
|
||||
where in this case $\underline{C}_k(x) = -\infty$ for $x
|
||||
where in this case $
|
||||
\begin{ccTexOnly}\underline{C}\end{ccTexOnly}
