%0 Journal Article %A Aceto, Luca %A Frutos Escrig, David De %A Ingolfsdottir, Anna %T Trace simulation semantics is not finitely based over BCCSP %D 2017 %@ 0324721X %U https://hdl.handle.net/20.500.14352/17910 %X This note shows that the trace simulation preorder does not have a finite inequational basis over the language BCCSP. Indeed, no collection of sound inequations of bounded depth is ground-complete with respect to the trace simulation preorder over BCCSP even over a singleton set of actions. %~
