Abstract : Esterel is a synchronous programming language where processes interact through signals. The logical semantics of this language express the meaning of each syntactic constructions, knowing {\em a priori} the set of emitted signals. Nevertheless, a special case have to be made for local signals, making the semantics non-deterministic. In this paper, we propose a new logical semantics where the rules are deterministic. We formalise some correspondences for usual definitions (coherence, reactivity, determinism, correctness) between the two semantics. These correspondences are formally proved in Coq.
