The prefix of bound variables \isasymAnd$x\sb{1}$~\dots~$x\sb{n}$ can be
ignored most of the time, or simply treated as a list of variables local to
-this subgoal. Their deeper significance is explained in Chapter~\ref{ch:Rules}.
+this subgoal. Their deeper significance is explained in Chapter~\ref{chap:rules}.
The {\it assumptions} are the local assumptions for this subgoal and {\it
conclusion} is the actual proposition to be proved. Typical proof steps
that add new assumptions are induction or case distinction. In our example
