Summary:Abstract: "This paper addresses the problem of defining a formal tool to compare the expressive power of different concurrent logic languages. We refine the basic notion of embedding [13] by adding some 'reasonable' conditions, specific for concurrent frameworks. The new notion, called modular embedding, is used to define a preorder among these languages, representing the different degree of their expressivity. We show that this preorder is not trivial (i.e. it does not collapse into one equivalence class) by proving that Flat CP cannot be embedded into Flat GHC, and that Flat GHC cannot be embedded into a language without communication primitives in the guards, whilst the converses hold."
