PRELIMINARY CALL FOR PAPERS CTRS-94 FOURTH (AND LAST) INTERNATIONAL WORKSHOP ON CONDITIONAL (AND TYPED) TERM REWRITING SYSTEMS July 13-15, 1994 Jerusalem, Israel CTRS 1994 will take place in conjunction with ICALP-94 at the Hebrew University in Jerusalem, Israel. There will be a minimal of overlap between sessions at CTRS and ICALP. This workshop is the fourth in a series dedicated to conditional term rewriting and other extensions of term rewriting systems, such as typed systems, higher-order rewriting, graph rewriting, combinator-based languages, constrained rewriting, etc. (The current plan is to merge CTRS with RTA beginning with 1996.) Previous workshops were held in Orsay (France), Montreal (Canada), and Pont-a-Mousson (France); proceedings were published in Springer's Lecture Notes in Computer Science series. Original papers in any of these or related areas are solicited for presentation and discussion at this workshop. An extended abstract of at most five pages should be sent to one of the organizers by post or (preferably) by electronic mail (in Postscript) by February 15, 1994. Anyone planning on attending should register for ICALP and make local arrangements through the ICALP organizers. Student rates are available.
