Conference proceedings 1995g Systems, CTRS-94, held in conjunction with ICALP ‘94 in Jerusalem, Israel, in July 1994..The volume reports the research advances in the area of rewriting in general achieved since the predecessor workshop held in July 1992. Among the topics addressed are conditional term rewriting, typed systems,

Associative-commutative superposition,. The calculus is parametrized by a selection function (on negative literals) and a well-founded ordering on terms. It is compatible with an abstract notion of redundancy that covers such simplification techniques as tautology deletion, subsumption, and simplification by (associative-commutative) re

A calculus for rippling,lthough it has been suggested that rippling can be implemented directly via first-order term rewriting, we demonstrate that this is not possible. We show how a simple change to subterm replacement and matching gives a calculus for implementing rippling. This calculus also allows us to combine rippli

Equation solving in geometrical theories,hanization of these geometries is done using their associated positive/negative conditional term rewriting systems. To any figure and to any property of the figure are associated two terms .. and .. such that the figure possesses the property if and only if .. and t. have a same normal form for the

Preserving confluence for rewrite systems with built-in operations,ical term rewriting system with a computation relation does in general not lead to a canonical simplification relation. We show how a canonical simplification system can be constructed for such rewrite systems with built-in operations. Decomposition free simplification systems never need to look at

Relative normalization in orthogonal expression reduction systems,ables and substitutions. To generalise the normalization theory of Huet and Lévy, we introduce the notion of . with respect to a set of reductions . or a set of terms . so that each existing notion of neededness can be given by specifying . or .. We imposed natural conditions on ., called ., that ar

On termination and confluence of conditional rewrite systems,lts for unconditional term rewriting systems (TRSs) which are non-overlapping or, more generally, locally confluent overlay systems. These results provide sufficient criteria for termination plus confluence in terms of restricted termination and confluence properties (Gramlich 1994a). Here we genera

How to transform canonical decreasing CTRSs into equivalent canonical TRSs,es with the class of orthogonal and terminating, unconditional term rewriting systems (TRSs). TRSs being included in CTRSs, this result follows from a transformation from any ground-confluent and decreasing CTRS specifying a computable function . into a TRS with the mentioned properties for . The ge

Termination for restricted derivations and conditional rewrite systems, Second, the relationship between forward closures and innermost rewriting will be discussed. This leads one to consider completion limited to innermost derivations. The ability to easily extend innermost and outermost forward closures is examined.
