A talk by Thanos Tsouanas

Our visitor Thanos will speak Tuesday (22 Jan) at 14h in Salle Marcel-Paul Schützenberger. Game semantics for disjunctive logic programming by Thanos Tsouanas Denotational semantics of logic programming and its extensions (by allowing negation, disjunctions, or both) have been thoroughly studied.  In 1998, a game semantics was given to definite logic programs by Di Cosmo, Loddo, …

Thanos Tsouanas visits for two weeks

We have a visitor to the team during the next two weeks.   Thanos Tsouanas http://perso.ens-lyon.fr/thanos.tsouanas/ is doing his PhD at ENS Lyon with Olivier Laurent.  Part of his PhD (via a Marie Curie fellowship)  requires him to undertake a “secondment” at a school outside ENS Lyon.  Thus his visit here.
