February 2012 : Zoltan Esik (Department of Computer Science, Szeged University) visited LIGM 1 month in February 2012. He initiated with Arnaud Carayol a work on the characterization of synchronizations trees definied by systems of functional equations. Together with Luca Aceto and Anna Ingólfsdóttir (School of Computer Science Reykjavik University), they obtained a full characterization for first-order systems. This work provides a unified approach to several classes of synchronization studied in the context of process algebras.
