Syntax and Semantics interacting in a Minimalist theory

After several proposals of a logical account of minimalism [5, 4, 6, 1], on the basis of the formalization provided by Edward Stabler [7, 8], we explore more precisely the interface between syntax and semantics. The main idea is that, according to many observations made for instance by Ray Jackendoff [3], the logical form is not the mere result of a derivation after the consumption of formal features. Indeed, there are rather two tasks which are performed on a par : the syntactic analysis properly speaking and the semantical analysis. Both analyses are connected by synchronization links in such a way that a parse can crash for (at least) two reasons : either because of a mismatch of syntactic features, or because of a failure in the semantic derivation.
