Titre / Title: Traces Infinies
Abstract : This report contains the chapter on infinite traces of the Book of Traces edited by V. Diekert and G. Rozenberg to appear in World Scientific (Singapore).
Different notions of infinite traces are introduced and studied: real traces, complex traces and transfinite traces..
Next, we focus on the partial order set structure induced by the prefix relation on real traces and on transfinite traces. We prove completeness results and algebraicity results for the poset of real traces and for the poset transfinite traces. The poset of real traces is in fact the ideal completion of the poset of finite traces.
Then, we define an ultra metric on the set of complex traces. We prove that this metric space is compact and is the metric completion of the monoid of finite traces.
Finally, we deeply investigate the properties of the rational languages and of the recognizable languages of real traces and of complex traces.
