F. Schernhammer, B. Gramlich:
"Termination of Lazy Rewriting Revisited";
Report No. E1852-2007-01, 2007; 31 pages.

Lazy rewriting is a proper restriction of term rewriting that dynamically restricts the reduction of certain arguments of functions
in order to obtain termination. In contrast to context-sensitive rewriting, reductions at such argument positions are not completely forbidden but delayed. Based on the observation that the only existing (non-trivial) approach to prove termination of such lazy rewrite systems is flawed, we develop a modified approach for transforming lazy rewrite systems into context-sensitive ones that is sound and complete with respect to termination. First experimental results with this transformation based technique are encouraging.

Lazy rewriting, termination, context-sensitivity.
