Computer Science Logic 9th International Workshop, CSl '95, Annual Conference of the EACSL Paderborn, Germany, September 22-29, 1995. Selected Papers

This book contains a carefully refereed selection of papers presented at the 1995 Annual Conference of the European Association for Computer Science Logic, CSL '95, held in Paderborn, Germany, in September 1995.
The 27 revised full papers included were selected after two rounds of reviewing from a total of 74 submissions for presentation at the conference and present the state-of-the-art in the area. Among the topics addressed are temporal logics, rewriting systems, deduction, theorem proving, process algebra, linear logics, proof theory, formal languages, and others.
