The formulas for $\theta$ depend on three fixed polynomials $F_1(c)$,
$F_2(c_0,c_1)$ and $F_3(\varphi,k)$ in the $g_{\nu\alpha\beta}$'s,
which we admit, are rather ugly. So we prefer to assert their existance
and postpone displaying them to a few paragraphs later.

\begin{technicality} \label{tech:nonseq}
Some Reidemeister moves create or lose an edge 
and to avoid the need for renumbering it is beneficial to also allow
labelling the edges with non-consecutive labels. Hence we allow that, and
write $\ip$ for the successor of the label $i$ along the knot, and $\ipp$
for the successor of $\ip$ (these are $i+1$ and $i+2$ if the labelling is
by consecutive integers). Also, by convention ``$1$'' will always refer
to the label of the first edge, and ``$2n+1$'' will always refer to the
label of the last. \endpar{\ref{tech:nonseq}}

\begin{clarification} In Theorem~\ref{thm:RelativeInvariant}, $\alpha$
and $\beta$ stand for {\em edges} and not for their serial numbers, which
may change if edges are numbered sequencialy when a Reidemeister move
that changes the overall number of crossings is performed. It is for this reason that we've introdcued
Technicality~\ref{tech:nonseq}.

\begin{proviso} A further minor issue arrises if $\alpha$ and $\beta$
are distinct before a Reidemeister move is performed but become the
same after the move (see an illustration on the right).

Indeed
Reidemeister moves may changes the indexing $\alpha$ and $\beta$ of
edges even when those edges are far from the move location, while it
makes sense to keep points like $a$ and $b$ in place when the moves are
away. Furthemore and more importantly, the distinction between $a<b$
and $a>b$ when $a$ and $b$ are on the same edge matters below.
