We have discovered the way to unify them, both in an observational framework and by means of a quite small set of parameterized (in)equations that provide a sound and complete axiomatization of the preorders that define them. In more detail, we have proved that we only need a generic simulation axiom (NS), which defines the family of constrained simulation semantics, thus covering the class of branching time semantics, and a generic axiom (ND) for reducing the non-determinism of processes, by means of which we introduce the additional identifications induced by each of the linear time semantics.engjournal articlehttps//doi.org/10.1016/j.entcs.2009.07.093http://www.sciencedirect.com/science/article/pii/S1571066109003156restricted access004ProcessesLinear time-branching time spectrumEquational semanticsUniform presentationInformática (Informática)1203.17 Informática
