NAPAW 92: Proceedings of the First North American Process Algebra Workshop, Stony Brook, New York, USA, 28 August 1992 (Workshops in Computing)

This proceedings contains fourteen papers on process algebras presented at the First North American Process Algebra Workshop, held on 28 August 1992 in Stony Brook, New York. NAPAW was held in conjunc- tion with CONCUR 92. It is hoped that NAPAW will be held yearly to bring together researchers from the North American continent interested in process algebras. We would like to thank the program committee members for reading through the abstracts, and Scott Smolka whose encouragement and assistance was critical to the success of the workshop.
