The workshop Infinite Traces was held at Tübingen, Hotel Hospiz, from January 23 to 25, 1992. The idea to this workshop was born at the general ASMICS meeting at Menaggio. It is the second ASMICS workshop on Free Parially Commutative Monoids, the first one was held at Kochel 1989. Whereas the Kochel workshop gave an representative overview over the different activities in the research field, the subject of the new workshop was restricted to the special theme of infinite traces with the aim of gathering only few experts.

The workshop was attended by 8 participants from six different European universities and in addition by three guests from the University of Stuttgart. The scientific programme started with lectures on Thursday, January 23 and ended at noon of Saturday January 25, 1992. In the afternoon of Saturday there was an excursion to the famous Hohenzollern castle at Hechingen about 30 km South of Tübingen.

The good working athmosphere at Hotel Hospiz and the active collaboration made this meeting to a successful event. We thank all participants for their contribution. We would like to express our gratitude to ASMICS and the Institut für Informatik of the University of Stuttgart for financial and other support. In paricular, we thank Heike Photien for local help. Last, but not least we thank Frau Elke Veihelmann from Hotel Hospiz for the warm and kind reception.
