Basic process algebra with deadlocking states

نویسنده

چکیده

Bisimilarity and regularity are decidable properties for the class of BPA (or context–free) processes [CHS95, BCS96]. We extend BPA with a deadlocking state obtaining BPAδ systems. We show that the BPAδ class is more expressive w.r.t. bisimilarity, but it remains language equivalent to BPA. We prove that bisimilarity and regularity remain decidable for BPAδ. Finally we give a characterisation of those BPAδ processes that can be equivalently (up to bisimilarity) described within the “pure” BPA syntax.

Deadlocking States in Context-Free Process Algebra

Recently the class of BPA (or context-free) processes has been intensively studied and bisimilarity and regularity appeared to be decidable (see [CHS95, BCS95, BCS96]). We extend these processes with a deadlocking state into BPAδ systems. Bosscher has proved that bisimilarity and regularity remain decidable [Bos97]. We generalise his approach introducing strict and nonstrict version of bisimila...

Generalized states on EQ-algebras

In this paper, we introduce a notion of generalized states from an EQ-algebra E1 to another EQ-algebra E2, which is a generalization of internal states (or state operators) on an EQ-algebra E. Also we give a type of special generalized state from an EQ-algebra E1 to E1, called generalized internal states (or GI-state). Then we give some examples and basic properties of generalized (internal) st...

BCK-ALGEBRAS AND HYPER BCK-ALGEBRAS INDUCED BY A DETERMINISTIC FINITE AUTOMATON

In this note first we define a BCK‐algebra on the states of a deterministic finite automaton. Then we show that it is a BCK‐algebra with condition (S) and also it is a positive implicative BCK‐algebra. Then we find some quotient BCK‐algebras of it. After that we introduce a hyper BCK‐algebra on the set of all equivalence classes of an equivalence relation on the states of a deterministic finite...

STONE DUALITY FOR R0-ALGEBRAS WITH INTERNAL STATES

$Rsb{0}$-algebras, which were proved to be equivalent to Esteva and Godo's NM-algebras modelled by Fodor's nilpotent minimum t-norm, are the equivalent algebraic semantics of the left-continuous t-norm based fuzzy logic firstly introduced by Guo-jun Wang in the mid 1990s.In this paper, we first establish a Stone duality for the category of MV-skeletons of $Rsb{0}$-algebras and the category of t...

Frame-Based Process Logics

abstract. We consider frames that can be deened by polynomials over states and transitions. States are elements from the natural numbers with pairing, and (state-)transitions are labeled with actions from some nite set. We study a connection with process algebra: pointing a frame by distinguishing either two states that function as a root and a tail, respectively, implements a terminating proce...
